Install Internet Security Software For Your PC

The importance of installing Internet security software on your PC can not be overstated. In my case, our family has six computers that are used by various family members. The Comcast Internet Security Suite by McAfee is a great value. With the proliferation of viruses, worms, malware, and intrusive cookies, a computer will become corrupted in no time flat when surfing the Web even if you don’t download anything online. Just simply hooking up your computer to the Internet and navigating to a few hazardous websites that you might not be aware of, will attack and download software in the background which will corrupt your computer and the worst part about it is you won’t even know your computer has become infected until it’s too late.

Internet Security Issues

Intrusive software that are security hazards such as PC key loggers can automatically track your key strokes when you type in your user names and passwords into online banking websites or even when you log in to your online email is just an online mouse click away. Many times this software gets loaded on your computer when you click on a window that pops up, and the popup makes it look like you have a virus on your computer. By simply clicking on the scan button of this pop up window, you are actually installing another malware program in the background. Don’t fall for this scam. It occurs so easily, even when users are aware that this can happen; it is easy to click the close button by thinking that the “X” close box closes the window with nothing else to worry about. However, don’t assume the close X button on a pop up window is the actual close button for that window. I suggest right clicking on the tab at the bottom of the Windows screen, and select the button that says “Close” on the pop up that you actually wish to close. Also it is wise to have a pop up blocker for your browser. I particularly like Firefox and even the new Google Chrome browser for the excellent popup blocking features.

Spyware, Malware, Adware, and Computer Virus Definitions

  • Spyware is computer software that is installed surreptitiously on a personal computer to intercept or take partial control over the user’s interaction with the computer, without the user’s informed consent.
  • Malware, is a blended word from the words malicious and software, which is software designed to infiltrate or damage a computer system without the owner’s informed consent. The expression is a general term used by computer professionals to mean a variety of forms of hostile, intrusive, or annoying software or program code.
  • Adware or advertising-supported software is any software package which automatically plays, displays, or downloads advertisements to a computer after the software is installed on it or while the application is being used. Some types of adware are also spyware and can be classified as privacy-invasive software.
  • A Computer Virus is a computer program that can copy itself and infect a computer without permission or knowledge of the user. The term “virus” is also commonly used, albeit erroneously, to refer to many different types of malware and adware programs.

Sad Business ManComcast Has Done It Right

I am really impressed with the marketing strategy from Comcast to their customers. With Comcast keeping their customers’ PC computers running free of viruses, with a free Internet security software tool, enables their customers to operate at a higher level of Internet protection than most of their competitors. Most ISPs simply provide you online Web access, with an attitude of “you’re on your own now,” which simply leaves way too much room for PC problems down the line. Computers are the tool to navigate the Web. If your computer is giving you grief, you are not going to have a very good user experience online. Likewise, if your computer runs trouble free, your life online will be like a breath of fresh air.

What if I am not a Comcast customer? Google Pack comes to the rescue.

Google provides a couple of free basic programs as part of their Google Pack for detecting and removing viruses and spyware.

Google Pack includes a special edition of Norton Security Scan to help you evaluate your computer’s vulnerability to security risks. Norton™ Security Scan is a free, easy-to-use tool that scans your PC for viruses, spyware, and other threats. » Download Google Pack.

Key Features of Norton Security Scan

* Scans for threats residing on your PC
* Detects and removes viruses, worms, and Trojan horses
* Warns you of spyware and unwanted adware
* Schedules regular scans
* Automatically receives updates**

Take the next step and prevent infections before they happen. Protect your system 24 X 7 with our award-winning Norton Internet Security™ 2009, designed to automatically block hackers, viruses, spyware and prevent online identity theft.

The other software tool from Google is Spyware Doctor Starter Edition which detects PC threats and removes spyware, adware, trojans and keyloggers. Spware Doctor Starter Edition includes Smart Updates and scheduling to protect your PC.

Both Norton Internet Security and Spyware Doctor can be downloaded directly from the Google Pack software installer page.

There are other free antivirus software programs available online. I have not tried very many of the free software programs that are available, so I can’t give you my recommendations. I would however suggest reading closely the reviews of what others have to say about the various free programs available for download. Be careful from where you download too. I believe a good place to get started is at CNET download.com for Antivirus Software. Note that the sponsored matches are displayed first. Two software programs that I have used in the past for detecting adware, spyware, and malware are Spybot – Search & Destroy©® and Ad-Aware by Lavasoft.

A general rule that should always be followed when installing antivirus software, is always use some form of threat protection software, but don’t use more than one type in automatic detection mode. The reason is the software programs will be fighting each other in the Windows Operating Systems and will be identifying the other software as a virus, spyware, adware, or malware program.

The best antivirus software programs will constantly update their database of spyware signatures and virus definitions and provide automatic PC updates for your local signature database. This is an extremely important point to be aware of because the virus threats are constantly morphing from computer terrorists all over the world, that are looking for ways of creating online havoc for everyone. You need both real time PC protection and automated deep scan protection. If you have an old copy of a PC anti-virus software, that has not had your local computer database updated to current virus signature threats, you are driving a computer on borrowed time, with no brakes, headed down a steep grade, just waiting for the head-on computer crash. Given the severity of the online PC virus threats (through both emails and web surfing), along with spyware, adware, and malware programs lurking on websites, your computer could very well end up with the blue screen of death. At the very least, your computer will become corrupted, slowed down to a crawl, performance will continue to suffer when trying to do anything, system resources will be tied up with running background programs that you are not aware of, memory usage will skyrocket, your hard drive will constantly be ca-chunking away, and you will think you need a brand new computer. I would venture to say that the majority of people that think they need a new computer are probably facing years worth of unsafe computer practices. Even if you buy a new computer and do not set up “best computer practices”, you are very likely to start the downward spiral all over again, because you invariably will want to copy your corrupted files, pictures, and programs over to the new computer. And, you will once again get on the PC merry-go-round, where you will certainly end up visiting the same websites, surfing new Internet sites where the online threats reside, and downloading and installing new virus infected software programs which will ultimately affect your PC’s health.

From a consumer standpoint trust me when I say, take the small amount of time now to get your online computer house in order. If you don’t take computer protection preventative measures now, you will surely be taking extensive time measures and creating PC headaches for yourself in the future just by surfing the web unprotected.

Article updated 12/17/11: Very Important! High Quality Low ESR capacitors, computer motherboard grade, 105ºC, 10mm X 16mm, caps are available for sale in kit form.

The logic board capacitor sizes included in the kits, are the original sizes of the capacitors on the logic board; making your job much easier to replace them. Important Note: The caps are a perfect fit for both diameter and height requirements, which is very important for the caps’ clearances to the back cover and extremely close mounting requirements. Reference the article: Fat Caps & Ripple Current for more electronics engineering & design insights.

International shipping is available for most countries worldwide. If your country isn’t listed for a shipping destination, please let me know to add your country to the list. Please provide your full name (first and last name) when ordering capacitors. Please refer to the Shipping Page for ordering and shipping information.

Send me an email if you would like to purchase ten or more iMac G5 cap kits, along with a note of which of the different cap kit sets you are interested in. Note: Apple early and late model iMac G5s with the PowerPC processor have different quantities of caps required on the MOB. Capacitor information is provided at my secure eCommerce website. Visually verify what capacitors your Apple iMac requires based on the pictures, and bring your iMac G5 back to life today.

Send me an email with any questions, or other special order requests. I have the power supply cap kits available too. Compare your PSU to the pictures. Feel free to contact me any time, with any questions. Take a look at the PSU cap kits that are available for purchase.

Apple iMac G5 Motherboard PowerPC capacitors replaced. The iMac mother board pictured above shows the locations of the new capacitors installed. Note: The heights and diameters of the new capacitors are slightly bigger in this picture, than the original caps. Upgraded to 1,800 uf 10 volts from the original 1,800 uf 6.3 volts. Please note these were larger diameters and taller than the original ones. They were a very tight squeeze between each of the caps. Back cover still clears (barely clears) all components. This information is for documentation sake. I don’t really recommend going up in the heights and diameters here. That is why I am selling the proper size caps for the mother board. If higher voltage caps, with the correct capacitance, good maximum current ratings, low ESR ratings, and temperature ratings were available, in the same exact physical case sizes, it would be OK to install those. However, higher voltage caps are not available in this size packaging.

Important notes are as follows. It appears as though lead free solder was used and a polymer was coated on the assembled motherboard on the bottom. A very hot soldering iron is required. Doing it yourself is not for the faint at heart. But fear not, you can do it if you follow this procedure.

It’s pretty easy to open the iMac case (first and second generation iMac models) and visually look at the caps. Simply lay it face down on a soft cloth. Loosen completely, the three screws on the bottom edge (Note: the screws will stay in), then just lift the back cover off from the bottom up. Visually inspect the capacitors for signs of expansion or tops that are rounded even slightly are an indication of bad caps.

Once you determine the status of the caps, then everything has to be disassembled, beginning with the removal of the power supply, which also can be a victim of bad caps and/or poor engineering, (see: DIY G5 power supply repair) in order to get to the bottom of the motherboard. Refer to the various Apple iMac G5 user and do-it-yourself part replacement manuals for details and visual instructions on how to remove various items. The cover is easy to take off by simply turning the three screws completely counter clockwise on the bottom of the computer’s lower edge and then lifting up the rear cover. The power supply (see: Apple Power Supply Removal and Replacement Instructions) then can be removed by unscrewing the mounting screws and disconnecting the main plug and the ambient light sensor cable (if you have an ambient light sensor model) to the motherboard, and partially turn the middle screw (about 5 turns clockwise) on the bottom of the case, which releases the back cover clamp, and the PSU will then lift out. Be careful not to damage the automatic ambient light sensor mounted on the bottom edge of the power supply unit. See this YouTube Video for what is inside the iMac G5 Computer. However once the cover is removed, the rest of the computer disassembly is quite a delicate task for most non technical people and requires special tools. Apple never actually intended for the end user to remove everything that I removed in order to get to the root of the matter.

A Torx screwdriver is not necessarily needed, though it would be helpful to use one. Check out the very handy magic screwdriver with the telescopic shaft with various size TORX bits for the mother board and other items. I had some precision screwdrivers that fit somewhat precisely in the fasteners, but it certainly would have been easier if I had the Torx screwdriver to begin with.

Here are some additional service notes and soldering tips. In addition to requiring a super hot soldering iron, one with good heat transfer and quick heat recovery, (a 60 watt soldering iron minimum is recommended) you may also need to grind off some of the polymer resin that is on the bottom of the circuit board, covering the capacitors’ leads, in order to get access to the lead free solder in the first place. See Soldering Tips for Lead-Free Soldering for detailed soldering tips and information. A proper soldering iron will make your job much easier and be able to quickly remove the capacitors from their mounts without having to do any special resin removal. I suggest ordering wider soldering tips, for use with a good quality soldering iron for a hotter and faster concentration of heat transfer. Soldering TipsIf you don’t use a hot enough soldering iron, the solder will never melt; you will just barely heat up the circuit board, and the capacitors will not come out. Also, if you have to
o small a tip, the heat will not transfer to the mother board very well, and the tip will cool down too fast when trying to melt the lead-free solder. If anyone would like to make a suggestion for a good quality soldering iron, at a reasonable price, with quick heat recovery, that can melt the lead free solder on this Apple motherboard, let us know here.

CHIPQUIK at JWestSales.comWhile removing the 20 capacitors on the G5 logic board, I experienced broken leads from capacitors that were falling apart, and leads that pulled out of the capacitors themselves, because of the extra heat that is required to melt the lead free solder in the first place. Note the following section is included for information purposes only. Some folks have recommended I remove this reference to drilling the circuit board holes out. While this is not a recommendation of circuit board drilling, I have included it here only as to what I had to do to fix the problem. Others may have a much better “hole” cleaning solution. In fact, I highly recommend reading about the “pin point tip” desoldering trick, the new Chip Quik desoldering alloy and flux, and the importance of using a proper soldering iron first. To begin with, I had to use a Dremel power tool in various ways, though with a hotter and greater wattage soldering iron designed for lead-free soldering, which I bought for future MOB repairs, the following would have been a non issue. Prior to removal of the G5 caps, it was first necessary to grind off the polymer resin and some of the excessive lead lengths from the old capacitors with a small grinder tool attached to the Dremel, and then drilling out some circuit board holes with a number 72 (0.0250 inch) solid carbide drill was what I did when the old cap leads broke off in the holes of the printed circuit board. Beware of, drilling the holes out could damage the circuit board and break carbide bits inside the holes. That would not be good and making it most difficult to fix. Suggest using the Chip Quik desoldering product here instead of drilling out the pads on the PCB. Also note that drilling the holes can damage the through platting which is designed for connecting the top and bottom hole surfaces of the PCB, and might also be used for connecting to other traces and layers of the multilayer PC board. This would also make for a really bad through solder hole connection on the new capacitors being installed.

When replacing the capacitors it is important to note which are the positive and which are the negative leads when installing in the board. New capacitors generally have a long and short lead (short lead is usually the negative lead) along with a negative indicator written on the side of the cap itself. Warning: Do not install capacitors in backwards, or you will blow up the new caps and possibly damage the circuit board. The circuit board has the positive hole marked on the printed circuit board itself. Here is a how-to demonstration of how to replace capacitors. Also, keep in mind when soldering your new capacitors to the motherboard, if you just have a round blob of solder on the bottom of the board, without it fully flowing through the holes, you can have cold solder joints. If you place heat on the legs of the caps for too long, you can also damage the new capacitors. A very hot soldering iron with quick heat recovery, and a wide tip is the best solution. See notes above about the recommended soldering iron. More information at: Soldering Tips For Lead-Free Soldering.

Special Attention to Details Area. At this point in the iMac repair process, after the new caps are completely installed, and properly soldered in the holes on the motherboard, you must trim off the excess new caps’ lead lengths on the bottom surface of the motherboard. Take a pair of diagonal cutters, and snip the leads to the proper lengths, making sure you do not get any metal fragments lodged in the motherboard or inside the chassis area of the iMac computer. Failure to cut the leads to the proper lengths could result in short-circuits, damaged capacitors, blown electronic components, and a blown iMac motherboard or power supply unit.

iMac Logic Card Bottom Side View

Once the capacitors are replaced on top of the motherboard, then it is time to reinstall the motherboard back into the chassis. Pictured above is the bottom of the MOB logic card, with the small square just to the right of the “.com” which is the location of the main processor (CPU) that protrudes from the bottom of the logic card. Do not try to remove this processor chip. Clean this area and the metal heatsink area that matches up to the CPU with alcohol, and apply fresh heat sink compound. I suggest when ordering the capacitors that you also order the thermal paste heatsink compound at the same time. You can order the thermal compound online from my J West Sales Store.

From George T.

“First off, the cap replacement fixed all the prior problems: i) endless blue screen on normal boot but OK with safe boot; ii) video breakup and horizontal bars; and iii) excessive fan speed. Now to the issue at hand…

The first thing the CPU does, based on ROM instructions, is check the RAM. If the RAM is OK the chime sounds. Therefore, if there is no chime, either the CPU is not working properly or a RAM chip is defective. This test covers the basic hardware and comes before the hard drive boot starts. The 3rd LED comes on early in the hard drive boot, but definitely after the chime.

My problem was no chime, and the reason was that the CPU wasn’t working. The CPU wasn’t working because I slopped some thermal grease over the circuit board items above the CPU. These items are marked “RAM clock” on the board.

Internet research revealed that the thermal grease is full of metallic silver. Furthermore, although there is little or no electrical conductivity, the grease is very capacitive. If it is sitting on the components, or even above the insulating copper tracings of the circuit board, it has low impedance at the clock frequency — it is a virtual short circuit. Once I cleaned off the grease, the board worked properly.

I would suggest that you incorporate this caution in your otherwise excellent instructions.”

Jim W. “Thank you George for the great insight.”

Arctic Silver Inc. manufactures a very good quality thermally conductive grease for modern high-power CPUs for Apple, Intel, and AMD, along with other high-performance heatsinks or water-cooling applications. Arctic Silver manufactures the Arctic Silver 5 product and the Arctic Silver Ceramique thermal compounds, and are world renown as being two of the best thermal heatsink compound options available. CPU Overclockers rave over Arctic Silver products.

When applying the Arctic Silver thermal paste compound (either the Arctic Silver 5 or Céramique 2), less is better, (see the warning on the left) paper thin is best. Please review instruction sheets for applying Arctic Silver 5 and also the Arctic Silver Céramique 2 instructions of use and proper application procedures. On Motorola chips, I use the covering of the whole surface with a very thin layer method as opposed to a dot in the middle method. Just be sure that very little if any comes out of the edge of the chip when the board would make contact with the heat sink. The way the application works is, the thermal paste fills the minor imperfections in the metal surfaces and removes the air spaces between the two joining metal surfaces and helps improve the heat transfer between the CPU and the heatsink. See image above for the the small square area right location, for the thin application of the thermal grease. Check out this Thermal Paste Comparison from Techware Labs review of the pros and cons of using the most popular thermal pastes available at the time the article was written. The article, while being somewhat dated, provides good insights into the differences between Silver Grease and Silicone Paste, and which is better for a computer CPU heatsink application. I would stay away from the silicon paste compound, because quite frankly, silicon paste or silicon grease does a poor job of keeping the CPU cool under load conditions based on the test results at that time.

Believe it or not, I have to say the finished project has worked like a champ. As a matter of fact, I have used the same iMac G5 here to do the pictures with a program called Skitch, and posting this article using Firefox running on the iMac too.

At this point in time, I’m not sure I would use any of those Rubycon Caps again. As the old saying goes, “Fool me once, shame on you; fool me twice, shame on me.” Rubycon, why did you use an improper electrolytic recipe? Was it cheaper to make those caps with the cheap electrolyte with the missing ingredient?

Rubycon MCZ Capacitors Bad CapsNote: I inspected my work a couple of weeks later, and decided to replace the five other capacitors also. I found some evidence online that these other capacitors go bad too. The 20 capacitors that I first replaced all looked good. Upgraded these five additional caps from the original factory installed 1,000 ufd, 16 vdc caps, to 1,000 ufd, 25 volts DC, operating temperature range: -55º to 105ºC. I should point out here that these were a larger diameter and taller than the original ones. They were a tight squeeze. I picked up both sets of capacitors at Halted Electronics a surplus store in Santa Clara, CA. They also have some new electronic components available at the store too. Generally speaking, it is usually OK, and advisable, to increase the DC voltage rating of the capacitors while maintaining the same MFD, microfarad rating. Don’t cut corners. As a suggestion, if you see any of the capacitors that have problems, it is highly advisable to replace the entire group of caps at the same time. If one or two of the caps are in the failure mode now, they would more than likely all be destined to fail in a very short time.

As an aside note, I included the previous paragraph information in this article as a historical troubleshooting and engineering evaluation note. I would suggest not installing surplus caps as a general fix for this problem and subsequently have installed “new” caps in this iMac. The problem with “old” surplus caps, you have no idea how old and long the capacitors have been sitting on the shelf with potential “shelf life rot”. I actually witnessed this capacitor shelf life rot on some of the first capacitors I looked at in the surplus bins before they got more from the back room. Many of the surplus caps are generic brands, or do not have proper low ESR ratings, or are general purpose capacitors that should not be used in mother board applications. Note that as of 8/15/2010, as I mention above, I upgraded this originally repaired iMac G5 with the surplus “old” caps to the proper sized and proper voltage rated “new” capacitors. Don’t shortchange yourself in your repair efforts here; order proper low ESR motherboard and power supply grade capacitors.

LED Indicator Lights

iMac G5 LED Indicator Lights

The LEDs on the main logic board (motherboard or MOB) indicate the following:
* LED #1 means it is detecting trickle voltage from the power supply unit, PSU. If you don’t see this LED, with the machine off but plugged in, it is not a good candidate for PSU repairs unless fuse is blown on the PSU itself, and the PSU should be replaced in this case.
* LED #2 comes on when the MOB sees all the correct powers (proper voltages present from PSU).
* LED #3 indicates the computer and LCD are talking (communicating) OK.
* LED #4 is strictly an overheating indicator LED, and should not go on under normal circumstances.

Another interesting bit of information regarding noisy iMac G5 fans and internal temperatures that I discovered after the G5 motherboard repair, it became apparent, the computer fans were running a lot quieter. No more Hoover Vacuum cleaner sounds. Also, the overall temperature of the computer is operating at lower temperatures in my opinion. I found this free Temperature Monitor program for keeping track both instantaneously and in a graph chart form, of what the CPU, Hard Drive, and Smart Disk drive temperatures are operating at. I did not have the program installed prior to the problem, but after I repaired the printed circuit board, I installed the temperature recorder and discovered that the CPU temperature does not get much above 65 degrees C, even with a warm ambient room temperature. The average temperature of the CPU is somewhere in the 58 degree C range (136 degrees Fahrenheit). Note: I keep my computer running for days and weeks on end.

I am still a bit ticked off that I had to go and do this myself. I had the Apple extended care warranty, but I missed out on the free repair by two months. If I had the problem occur two months earlier, Apple would have covered it free of charge. Apple never sent a message concerning the problem. It took some investigative work to find out that they had issues with the capacitors leaking, but they downplayed the severity of the problem.

This should not happen with a product three years old. In Apple’s defense I can tell you that I found evidence that many other computer manufacturers also had the capacitor problems from buying low cost capacitors from a stolen electrolytic capacitor recipe from Taiwan. See this video showing computer circuit boards with bulging, leaking, and exploded capacitors on board from a variety of computer manufacturers. While I am a fan of Apple products, I just have to say this is not one of their stellar computer products moments. I’m sure it was a business decision to not have a product recall, but I think they should have had one. Of course, I guess you could say, I’m a little biased on this issue.

Yes, the Apple Store folks were nice enough to take a look inside the iMac at the local Mac Genius Bar, and give me a heads up on what the problem was, though it only took a five second look inside for the Apple guy to tell me that I need a new motherboard, and oh by the way, the total cost (approximately $750.00) was going to be two thirds the cost of a brand new computer. The Apple Store guys suggested I buy a new Apple desktop computer, one that is faster and better.

I said, “not today.”

As one last thought before the night is over, lead free solder is a pain in the rear. Repairing all types of electronics is going to become increasingly difficult with these high temperatures required to remove and install new components in their place. We are becoming more and more, a disposable society.

Also, I think it is quite comical reading the Apple repair extension program especially the section about not fixing the desktop computer yourself, now that I have fixed it myself. And, the one that says if you don’t have any of these problems there is no need to do anything, “just wait for it to break after warranty,” my two cents added.

*** Just as a reminder, it is also a good idea to check your iMac G5 power supply. A bad power supply, will produce excessive ripple on the output voltages because of bad internal PSU capacitors, and can cause your new capacitors on the MOB to quickly fail. It is not hard to check the PSU caps. Go to the article on the Apple iMac G5 Power Supply for more detailed information and what you should be aware of. I have the complete PSU cap kits in stock. For a list of the capacitors required on the PSU, take a look at the Inside the Apple iMac information articles.

A Few Concluding Remarks

  • Do a quick visual inspection of the inside of your iMac G5 for bad caps.
  • Replace both types of caps completely even if one or two is visually bad, since it is most likely the other caps are in a failure mode too.
  • A good soldering iron or station is most desirable for this DIY project. Use good lead-free soldering techniques.
  • Inspect your iMac G5 Power Supply too. Bad caps in the PSU can directly affect the caps on the MOB.

Upgrading a Computer Hard Drive And Back Up Software

Important: Backup Your Computer Now, Before It is Too Late!

Hard DriveIs your computer hard drive running out of capacity? Are you wondering what you are going to do when it maxes out? Are you worried about loosing all your pictures and files when your hard drive crashes? Have you ever performed a computer HD backup? Well, I’ve got the solution for you.

No one really wants to go through and delete information from the past. Installing a second add on drive is a possibility. Another option is to install a brand new C drive, with all your existing programs and data intact.

There are a couple of programs that I am aware of that make it easy to clone a hard drive completely. The program that I have used for backing up information and cloning a hard drive is Acronis True Image. Acronis True Image is a program that once installed on your existing hard drive can be used for daily backups to another hard drive or to install a brand new C drive with all the existing files intact.

For example: I had a computer with a 180 Gbyte disk drive that was getting to the point, with pictures, videos, files, and programs installed, that the days were numbered until I was going to be forced into doing something about it. I decided to take the initiative and replace the disk drive with a new 400 GB disk drive. Using Acronis True Image, the new one is Acronis True Image Home 2009 backup and disk image recover software, I first did a fresh backup on the second disk drive I have installed in the computer. Once that was complete, I disconnected the second drive and hooked up the brand new Seagate 400 GB disk drive that I picked up from Fry’s Electronics for $89.00. I can’t believe these prices on hard drives keep dropping as much as they have over the years.

Once the second drive was hooked up, I ran the True Image software again, and cloned the primary drive, but expanded it to include the total available space to be used on the new drive. Once the cloning process was done, I then removed the first drive, and made the new drive the C drive, then re-attached the other backup drive, and the computer was up and running on the new hard drive.

It is interesting to note that even though most drive manufactures state a certain size hard drive, they usually overstate what the drive actually holds. It seems as though there is a 5 to 10% fudge factor. The Seagate 400 Gbyte drive turned out to be 367 Gbytes formated. But still, it is hard to pass up a deal when you need it.

My recommendation for anyone looking for a new hard drive, try to estimate what you will be using it for. If it is going to be used for pictures and video storage, then by all means up the storage capacity. However, if a standard 500 GB hard drive is substantially more than enough room for what you are currently doing, save your money for the future. As the price on these hard drives has dropped over the years, it is likely that the price of hard drives will continue to plummet, and the capacities will continue to increase. Then, the price per gigabyte will be less in the future, when you really need the storage. As of this update date: 2/20/08 – there are external 1 Terabyte hard drives available for sale around 100 dollars. See: 1 TB External Hard Drives
