The Floppy Disk Drive Engineering Design Challenge SSD to FDD

The challenge is to design a floppy disk drive interface to be a direct replacement for 3½-inch FDD or older 5¼-inch floppy disk drives on legacy industrial computer equipment. The FDD engineering hardware design requirements would be to build a new style FDD solid state disk drive, hooked up on the floppy disk connector (FDD). Keep in mind, the option to install is not available on legacy machines a solid state HD device — IDE to Compact Flash CF adapter on the parallel IDE HD connector since many industrial equipment machines do not support IDE; which by-the-way, these direct replacement hard drive adapters are currently available for PCs with IDE PATA ports (see images below). As part of the engineering guidelines, the direct replacement FDD device must also be able to read and write from FDD 1 to Solid State CF FDD 2 or vice versa.

FDD Engineering and Design Notes For Direct Replacement Floppy Drives

Message: “Jim: I have been searching for a replacement for a 3.5” FDD that reads/writes to a USB flashdrive or CF memory card.

Has the Engineering Challenge generated any solutions, yet?

I’m hoping ….

Thanks,

M”

Hello M,

I’ve gotten a bit of feedback in this area.

Apparently the signal conversion is a bit more difficult than meets the eye. I have spoken with some engineers that have a cursory understanding of the floppy disk system, but it seems the interface is more complicated than the HD solid state disk drive to an IDE port. This seems strange that a simple device (in concept) like this is not available. I would think there is an engineer out there that could do this, but so far haven’t heard from anyone that can do it.

Some people have a hard time understanding what it is being requested here.

They want to tell me that there are already external USB floppy drives. I have to tell them that is not what we need. We need a direct plug in to the FDD cable that reads/writes to a USB flashdrive or CF memory card.

Maybe I need to spell it out a little more concisely.

Email Jim today.

Many of the old industrial machines used in various product manufacturing industries, and continued to be serviced and supported throughout the manufacturing world today, especially that of the circuit board drilling equipment and PCB routing machines, along with legacy CNC metal fabrication and CNC plastic machining, mold cutting equipment, and die making machines still use either the 5¼ FDD or 3.5 inch FDD to load operating systems and store part programs on hybrid computers. These hybrid computers are not PC based and have no internal or external hard disk drives, nor are these industrial equipment machines capable of hooking up a hard disk drive through any type of IDE cable connector; since the computers do not have IDE HDD interface capabilities, nor do they have USB connector capabilities either. Other machine fields that are excellent candidates for a new style SDD FDD would include: commercial grade and high-end consumer models embroidery machine equipment, quilting machines, and programmable sewing machines used built-in floppy drives for storing patterns and job programs.

Other industrial machines were designed around the original IBM PC which preceded the “IBM XT” and included 5 ¼ inch floppy drives but no hard disk. There may not be very many of these types of machines still in existence or actively used in production today.

Machines that are still being used in production, but have their own hybrid computers, are typically using a proprietary floppy disk controller for reading and writing to the floppy disk drives. This makes disks written in the proprietary format, unable to be read with the standard PC format floppy drives.

New manufacturing equipment is very expensive. Many of these these older machines are still quite capable of producing products in a production environment, and their owners are not willing to throw them away to buy a brand new machine equipment that will produce the same amount of product, in the same amount of time.

History of the Floppy Disk Drive

Floppy drives have been around since 1971, when IBM was the first to introduce the 80 KB read-only 8-inch FD. Subsequently, IBM, Memorex, and Shugart introduced 8-inch RW SSSD and DSSD floppy drives that reached a storage capacity of 980 KB (CP/M) – 1.2 MB (MS-DOS FAT) in 1977. Then in 1978 the 5¼-inch DD was introduced which had a storage capacity of 360 KB or 800 KB. In 1982 the first 3½-inch HP single sided FDD came on the market with a capacity of 264 KB. 1984 marked the introduction of the Macintosh which used the 3½-inch (DD at release). It had a marked capacity of 1 MB, though it was more like 720 KB (400 KB SS, 800 KB DS on Macintosh, and 880 KB DS on the Amiga computer).

3½-inch and 5¼-inch floppy drives shared the market place from 1982 through the late 1990s and even some industrial equipment manufacturers continued to use 5¼-inch floppy drives just at the turn of the century, though most industrial equipment manufacturers switched to the 3½-inch FDD models long before. The floppy disk drives have now been largely superseded by USB flash drives, CD-ROMs and DVD-ROMs.

R&D and Investment Capital by US Industrial Equipment Manufacturers

How did we get into this FDD mess. Part of the reluctance for US industrial equipment manufacturers to design new industrial equipment, with using new style PC based controllers had to do with the costs associated with R&D investments in both hardware and software engineering and design. Also, because of the sizeable R&D investments which many of these companies had made in the past, with specialized dedicated computers that had worked well up until this time in a manufacturing environment, top management was reluctant to spend any more investment capital into designing what was already perceived as a solid engineering design. While US companies sat on their laurels, their foreign manufacturing counterparts had leapfrogged over the controller designs, and started building controllers that were using standard, over the counter, PC based controllers, with software written to run under a Microsoft Windows environment. Now, many of the US manufacturers have been hit hard by the foreign competition and are struggling mightily to compete once again in the world markets.

What we need, is a Floppy Disk Drive Solid State Bridge or FDD SSD

What is happening for many of the end users of this legacy equipment is simply that the floppy drives are wearing out. They are getting old, and with the lack of replacement parts available, the equipment is becoming obsolete. These end users need a floppy disk drive bridge to get them over the hump, especially in these difficult economic times. They need something cheap and easy, that would quickly interface to these old floppy disk drives with a simple FDD plug and play device that requires no software drivers to be installed on the computer. Ideally speaking, it would be based on the solid state drive design similar to the SDD HDD — solid state drive hard disk drive, but for a SDD FDD — solid state drive floppy disk drive hookup.

The demise of the floppy disk drive is making it more difficult to keep aging computer systems operational. Floppies are still used for emergency boot disks on many of these aging systems that lack support for other boot media such as CD-ROMs and USB devices. Even some of the Windows Operating systems such as Windows XP and Windows Server 2003 relied on third party drivers, loaded on floppies. Many of the BIOS and firmware update and restore programs require they be executed from a bootable floppy disk. And if heaven forbid, during a BIOS update something goes wrong, even as of 2008, a floppy disk is required to perform a BIOS recovery after a failed BIOS update attempt.

The music industry still employs many types of electronic equipment that use standard floppy disks as a storage medium. Equipment that is quite functional, and was quite expensive to purchase, and would undoubtedly be prohibitively expensive to replace such items in the music industry as: synthesizers, samplers, drum machines, and sequencers, all of which continue to use 3½-inch floppy disks. Other storage options, such as CD-R, CD-RW, network connections, and USB storage devices have taken much longer to mature in this industry. Source: Wikipedia — Floppy Disk Drive.

So, it makes sense to bridge the FDD storage technology gap between the old floppies and the newer storage device options of CDs, DVDs, external HDs, and USB storage devices.

SSD HDD — Solid State Disk Drives For Laptops, Notebooks, and PC & Apple Desktop Computers

Here are some examples of HDD solid state hard drive adapter devices that can be used on computers to replace the internal hard disk drives using an adapter plug and socket to install Compact Flash (CF). Besides the availability of hard drive adapters, a person can replace their internal hard drive with solid state drives. There are SSD HD IDE PATA for the older parallel ATA interface IDE internal hard drives and SSD HD SATA for the newer and faster serial ATA interfaces available too.

Floppy Disk Drive Bay Mounts and PCI Slot for IDE to Compact Flash Adapter

Addonics Technoloigies, located in the Silicon Valley, California, manufactures many types of adapters designed to be direct replacement devices for hard disk drives. Addonics offers a full range of storage devices based on various storage technologies – optical (CD, DVD, CDRW, DVD-R/RW), hard disk (3.5″, 2.5″, 1.8″ and Micro Drive), floppy, small digital media reader/writer and stand alone storage appliances. Most of Addonics products are designed to connect to different interface technologies – USB, Firewire, Serial ATA, CardBus, SCSI, IDE and all Windows operating systems. Some devices also have been certified to work under Linux, Mac and Solaris 8. Together with a set of complementary accessories – power cables, host controllers and adapters, Addonics products have been selected to deploy in various vertical markets and applications, including in some mission critical environments. Read more about Addonics’ storage solutions.

Many of their products are used to create your own storage size solid state HDD using Compact Flash card sizes of your choice and embed the devices in laptop and notebook computers’ HDD cavities. The item pictured above provides two slots to include both a master and slave HDD Solid State CF drive built into one compact unit. Single slot CF Hard Drive Adapters are available too. With the price of Compact Flash Memory dropping, it is very easy to see how this IDE HDD adapter to Solid State HDD could be utilized in both old and new notebook computers. To replace the internal laptop HDD drive requires simply removing the old 2.5” IDE hard drive from the 44 pin IDE connector and attach the CF adapter with the CF card inserted onto the 44 pin IDE connector with key pins matching. Then you simply tuck it away inside the old hard disk drive bay cavity with double faced tape. Read the details for this device, along with detailed illustration about replacing the hard drive with the Addonics CF HDD Adapter in a notebook or laptop computer. Adapters like this and others for the newer serial interfaces would be an excellent choice for both Apple laptops as well as any of the older PC laptops with either Microsoft Windows or Linux based operating systems.

A while back, I had the pleasure of speaking with a sales engineer at Addonics about the need for a FDD solid state replacement device. He was most helpful, but at that time, Addonics did not have anything available in the way of an adapter to go from floppy disk drives to compact flash or any other form of solid state storage. While he did mention that others had also contacted him over the years to design this type of device, he felt it would be expensive to develop the FDD solid state interface device for what was perceived as not having a very large demand for the product.

External Floppy using USB Interface

In recent years, because many of the computer manufacturers were not installing floppy disk drives into new computers, has brought about a need for an external floppy disk drive. Behold the USB plug and play Floppy Disk Drive.

A0769810 Before we get to the USB Floppy Disk Drive product, there was however a plug-in module device available from Dell Computers in the UK that plugged directly into the IDE interface cable from a motherboard to a 1.4 MB Floppy Disk Drive. The manufacturer was Origin Storage, with the manufacturer’s part number being listed as: CSERIES/FDD, and the Dell part number listed as: A0769810. Not sure if this floppy disk drive adapter hookup to an IDE parallel hard drive port is still available, or who would really need or be interested in this FDD to IDE port device today, but I thought it might be interesting to note it in this article. Also note that I was not able to find that particular FDD IDE device on Dell’s US website. Maybe it is an old out-dated link on Dell’s UK website. Like I said, I’m not sure there really is a need for this device. I don’t think we need to place floppy disk drives at the end of IDE cables, but it sure would be nice to store old system software from a floppy disk on legacy, non PC based and no IDE based machines, and boot to a solid state CF adapter on the FDD cable. Let’s build a solid state floppy disk drive as a direct replacement for a FDD.

USB Floppy Disk Drives — External USB Floppy Disk Drives

Some have asked, “why not just install a USB floppy disk drive on this old equipment?” Well, the biggest hurdle with this solution idea, is old non-PC based computers do not have the option for USB interfaces. Yes, you could install an external USB FDD drive on any PC that provided for USB devices to be installed, though there are generally Microsoft Windows software requirements for hooking up most of these external USB 3.5 inch floppy disk drives.

Others have even come up with a brainstorm of a solution of having some sort of Floppy Disk Drive to USB interface. In essence, this would involve going from the FDD cable into some sort of USB storage device. That might be a possible solution, but one would have to engineer an interface to go from the floppy pin-outs and reading and writing electronic signals requirements of the floppy disk drives, to a USB interface device that was a stand-alone, no drivers required plug-in adapter unit.

Sony Floppy Disk Adapter Sony developed the Memory Stick/Floppy Disk Adapter MSAC-FD2M. The MSAC-FD2M adapter was specifically created for the Sony Mavica FD-95 camera. SanDisk, SmartDisk, and Dane manufactured the FlashPath Floppy Drive Card Adapter for Smartmedia memory cards. These floppy disk adapters provided a slot in the edge of a floppy disk looking unit that Smartmedia cards could be inserted and then insert the whole 3.5 inch adapter into the camera or into a 3.5 inch floppy disk drive in a PC. The application was for those computers that did not have a built-in USB port, to be able to read the Smartmedia memory cards into the PC. With the addition of USB support in newer computers, these floppy disk adapters quickly faded off the landscape though you can still find them available in some online locations.

So that gives an overview of what is available for floppy disk drives, adapters, memory cards, and solid state disk drives.

FDD to USB Emulator Engineering and Design Project

On April 2008, Google Groups sci.electronics.design section, Jim F. wrote about his venture into building a floppy drive interface and the information he is seeking.

I’ve decided on a new project (this is for fun only) where I will build my own USB thumb drive to floppy interface. My intention is to replace the single floppy drive that exists in a particular piece of legacy test equipment. This will need to be a complete hardware solution (cpld/ucontroller) interface which I can remove the floppy and replace it with my USB floppy emulator.

I’ve really never given floppy technology much thought, so I figured it would be fun to go back to the 80’s and get acquainted with it…

I’ve been searching the web but haven’t had any real luck finding *good* technical data on floppy drive electrical interface data. I’ve read a few floppy drive specification data sheets, but they seem a bit lacking. Does anyone know of a really good repository for this information?

Thanks for any help that you can offer…

Jim

This is quite an interesting thread into building the floppy interface by creating a USB thumb drive to a FDD interface. Read more at sci.electronics design. I’m not sure what the status of his engineering design is currently, but it sounded like others would certainly like to see a device like this too. In the thread you will find more technical information into the engineering and design of this FDD interface project. If anyone has any further information into this FDD adapter interface project, please post your comments here or at the Google Groups Science Electronics Design posting. Considering the reduction in the cost of USB Flash Drives, this might very well be a viable solution for the FDD adapter project.

Universal Hard Drive Adapter IDE Laptop or Desktop SATA and PATA

Apricorn DriveWire – Universal Hard Drive Adapter

Apricorn Hard Drive Connector

SATA 2.5″ or 3.5″ Hard Drives and Parallel HDs, IDE 44 Pin Adapter, or IDE 40 Pin Adapter for Laptop Drives & Desktop Drives to USB Interface

Have you ever wanted to get information off an old Windows PC internal hard drive or just a dead computer? Maybe you have a dead Apple iMac G5, G4, or G3 and need to recover the data off the hard drive. Have you ever wanted to be able to install a new larger hard drive in your notebook computer, MacBook, MacBook Pro, or other Intel-based iMacs, or a desktop PC and do it quickly, with all the drivers, and software intact? Well, I’ve got the answer for you.

Here is a cool device from Apricorn that makes it easy to plug in any new or used internal hard drive from a laptop or desktop (Mac or PC), to any external USB port on another Apple MAC or a Microsoft OS PC.

Apricorn includes both the DriveWire hard drive adapter hardware, with AC power adapter, cables, and USB cable, and software to be able to clone virtually any PATA/IDE or SATA, 2.5 or 3.5 inch, hard disk drives.

The DriveWire provides a hi-speed USB 2.0 interface to: SATA, 40 pin PATA/IDE, and 44 pin PATA/IDE.

DriveWire is bundled with Apricorn’s “Upgrade Suite” which features the award winning “EZ Gig II” cloning software for Windows and “Shirt Pocket’s SuperDuper!” for Mac

Five Star Recommendation * * * * *

I have used this universal hard drive plug-in adapter quite extensively myself for all types of applications. I have cloned Apple hard drives, tested old parallel IDE disk drives, used it to backup old computer systems, recovered files off a bad PC, and used it as an external connection for a spare hard drive for both PC and Mac computers. People have used it to quickly backup their system on an old hard drive and then placed that backup into a secure fire safe, not to be touched unless all else fails. The HD adapter has been a lifesaver for me. I don’t like to touch a computer system unless I have a backup to begin with. You do not need to install any backup software or other special device drivers if you are just plugging in various hard drives.

Follow the simple instructions and make sure to set your IDE PATA hard drives only, to “Master mode” (not cable select) with the jumper setting on the hard drive, and you are set to go. Note, master mode is a jumper setting that only applies to 3.5″ PATA hard drives and determines which hard drive is the main device on the ATA bus. Most newer PC Bios systems and motherboards utilized cable select mode jumper settings on the hard drives to automatically identify which drive is the primary and which drive is the secondary based on cable hookup. In “Cable Select” mode, the black cable connector plugs into the primary master drive, gray cable connector plugs into the secondary slave drive, and the blue connector attaches to the computer motherboard or host IDE controller.

Once you have confirmed this important “master” jumper setting on the HD, then simply plug in one hard drive at a time to the DriveWire adapter and plug the USB cable into your USB port, and it shows up on your “My Computer” on a PC, or your desktop on a Apple Mac. You can copy and retrieve information from an old HD drive. That is the beauty of this plug-in device. Fast, easy to use, reliable, and really really handy too.

Pictured below, from left to right is the Apricorn adapter, USB cable, AC cable which plugs into AC adapter, AC adapter with drive plug, and software disk with both PC and MAC software included.

This device is great for IT departments, techies, and even the ordinary person that simply wants to easily plug in a hard drive to see what is on it. Check out the video on how easy it is to use.

How To Instructions For Cloning or Copying Old Laptop Hard Drives to Large Hard Drives – Article Addendum 12/15/08

Here is a question from a reader in Internet land about his laptop hard drive.

I have a question. I have a small laptop hard drive (dara-206000), 6GB ATA/IDE IBM Travelstar. I want to transfer all the data from this small hard drive to another hard drive with the same features. Does this universal hard drive adapter would work for me?

Here is the answer.

It depends on how you intend to use it. First off, if the hard drive is still in the laptop, then you need to have a USB 1.1 or USB 2.0 port available on your laptop to clone directly with the adapter to the computer’s internal hard drive. Then once you’ve done that, simply pull out the internal HD and replace it with the new higher capacity laptop drive.

If you have the hard drive in your hands, then you can copy the entire drive onto another computer then copy the the contents back directly onto your new hard drive and then install the new hard drive into your old laptop with all the software intact. You will probably need to use the included backup software to get all the system files transfered. You can also use backup software such as Acronis. See: Upgrading Computer Hard Drive and Backup Software

It’s important to note that the adapter is designed to only hook up one drive at a time to the output port of the adapter and then hook up the input to a USB port of a computer. The hard drive will show up as an external hard drive on the computer’s “My Computer” page for a Microsoft Windows OS PC or display on the desktop for an Apple Mac OS computer.

The Adapter is for SATA 2.5″ or 3.5″ Hard Drives and Parallel HDs, IDE 44 Pin Adapter, or IDE 40 Pin Adapter for Laptop Drives & Desktop Drives to USB 1.1 and 2.0 Interface.

Hope that helps explain the details of how to go about transferring the HD information from one HD to the other. By-the-way, you could even use the Apricorn DriveWire adapter to clone to a solid state hard drive – SSD HD too.

Best regards,

Jim

Fans, Power Supplies, Computers, and Power Outages

Talk about a confluence of power events…

Tripp-Lite UPSHaving a battery UPS backup system only works so long. San Ramon, California experienced a power outage that took out quite a large number of blocks. While talking on the cordless phone, the power went out, but I was still talking. How was that possible? OH yeah, I had the cordless phone plugged into the UPS. But, I was on Comcast Digital Phone Service, and yet it was still working. The Internet was down because the Comcast modem had no power, yet the Comcast Digital Phone Service was running strong. Sure enough when I went to a phone that was hard wired into the wall, and found the system was working just fine.

The alarm from the UPS was beeping continually. It was time to shut the computers down. Well, they shut down just fine, and an hour or so latter the power came back on, and everything started powering up no problem. However, a short while later, I smelt that familiar burnt odor, that says Ought Oh, there’s a problem, throughout the office. Looking over at the computer monitor, it was blank. The computer power supply light was out, and the smell was coming out from below the desk. Sure enough, the computer was dead. The power supply was red hot. Down to the bone yard to see if I had another power supply from one of the old hulks. Sure enough, I had a 300 watt supply in one of those stacks of computers awaiting reclamation. Actually, I’m somewhat of a pack rat, thinking that I’ll need something from all those old items. And, it usually works out that I end up using something that gets me through another predicament.

Power SupplyAfter installing the power supply, everything seemed to power up just fine.

This whole set of events started earlier with one of my small circulating fans going out for the office. The fan shaft and bushings were quite dirty and the fan had great difficulty turning on it’s own accord. After pulling that apart, and cleaning it up, I gave it a couple drops of my trusty Tri-Flow, teflon based lubricant (don’t leave home without it) and reassembled it. Sure enough the fan starting turning again. We’ll see how long it lasts.

Now back to the computer. Hopefully this 300 watt supply will last for a little while. I think it would be a good idea to check out a 400 or 500 watt power supply though. I have too many internal items running on this computer. Wow, just did a search online for power supplies and there are 550 and 600 watt supplies available too. Or, I could go for the Thermaltake Toughpower 1200w Power Supply. Now, that’s a lot of power!

FirefoxAn interesting thing happened when I came back online. Mozilla Firefox had upgraded itself, and some things changed on the configuration. Actually, I don’t think it actually upgraded, but something changed in the settings on the computer. My All-in-One Sidebar Toolbar had moved over from the right side to the left side. However, it added a new feature of automatically minimizing on the side when the mouse is moved off of it. This is actually a good feature, in that you don’t have to click anything to extend your browser window size. Also, my bookmarks were missing. Had to download them again from Foxmarks Bookmark Sync, which is a program for Firefox that allows you to synchronize your bookmarks across all your computer machines no matter where the computers are located.

Anyways, I’ll have to play with Firefox a little more to see what else has changed.

For now, it’s back to the Internet for some important items that I need to get done for some customers. I think some customers think things automatically happen with just a quick click of a button, and it’s done. But, that’s another story.
