External 5.25" Floppy Drives? 52

Posted by Cliff from the nostalgic-for-old-media dept.
R2.0 writes "Are there any external 5.25" FD's out there? My wife and I have a number of old 5.25" floppies with all sorts of interesting stuff from school - she had a Kaypro, and Lehigh had just gotten hundreds of Zenith PC's. In the interest of archival record keeping (Ok, I'm a packrat), I'd like to get this stuff off the old floppies and onto my HD, and then maybe onto CD-R. Problem: I'm out of 5.25" bays in my Dell, so I can't just put in one of those handy combo 3.5"/5.25" drives. And I can't just pop the CD player out, pop in an old drive, and do everything in one batch - I need to be able to do this a couple of disks at a time, between changing diapers, etc. Can anyone suggest an external solution to my problem? Parallel, serial, or USB; homebrewed or purchased." Ah, the endless problem of preserving data from old media. Due to the lack of use that 5.25" drives have had in the past 10 years, this might be a very hard-to-find item. Is anyone making 5.25" drives anymore?

    I've got an external "386" device (I paid like 1000 dollars for it) that I'd sell. It connects via the parallel port, or ethernet with the right drivers. As a bonus, it has 40 MEGABYTES of its own "hard disk" space and is a combo 3 1/2, 5 1/4, CD Drive.

    ...a few years back. I just stuck an old 5.25" drive in my machine and tried to do it all at once over a few weeks. I never did quite finish and now I'm in the same boat as you. However, I do have some old PC's sitting around.

    I pulled a working 386 out of the trash at work about a year ago. I'm thinking I could use the floppy drive on there and dump everything to the 100-some-old MB IDE harddrive and just plug that in to my regular machine to copy them all off... or pop an old network card into it, but that's probably too much work. I've also got pcAnywhere and that funky yellow parallel cable that came with it.

    The advantage I have is that I have quite a bit of old hardware sitting around. If you can't find a new drive, go to a computer consignment shop and pick one up. Or possibly even get an old '386 machine (or so) for less than $100 bucks.

    I don't know what the current availability of 5-1/4" drives is, but it's not too hard to get ahold of old computers these days. It seems almost everyone's got an old clunker in the closet or basement that you could borrow.

    Good luck!

    • Good luck to you. Several associates and myself have all had problems using old HD's, even IDE, in newer PCs. The ones that stand out are 386 salvage, a Maxtor 345MB and a hefty 40mb seagate. The BIOS seems to find them ok but windows and at least one flavor of linux had a fit when we got to the OS load.

      Damn I wish i got that seagate to work, it was only 40MB but it was still good (worked on the 286 it was pulled out of) and was built like a brick shithouse.

  • Get a dual 3.5/5.25 unit (assuming your floppy is wastefully mounted in a 5.25 bay). Or it sounds like you have a stack of 5.25's, just remove your CD-ROM/DVD for a night or two and copy them all over. Or if you feel you really need to have this 5.25 all the time, either get yourself a long floppy cable to replace your existing floppy cable and a couple of power cable extenders and just run the floppy external. Or find a SCSI floppy, but that might be too hard since I don't think you have any SCSI adapters. Or just get a real computer, you know one without a namebrand on the outside.

    As for the question of whether 5.25's are still made, I am sure Teac or somebody still pops out a few 5.25's and if they don't I am sure there are millions upon millions that are disused and availble for a pittance.

      Why on earth would you make such an unlikely assumption? The only time I've ever seen a 3.5 mounted in a 5.25 bay is in one of those combo plates that have USB and/or FireWire front ports in the extra space. It doesn't make sense to swap out such a unit for a dual 3.5/5.25 either permanently (you'd lose the front ports) or temporarily (in that case, just mount an old 5.25 until the disks are read and forget the 3.5/5.25 "dual" feature).

    We still have several control units on the mainframe that read their microcode off of a 5.25" disk that's held in each unit. I remember not too long ago we ran around the campus like mad trying to find a PC with a drive in it because we thought we had a bad microcode disk. Turns out, we didn't but we even resorted to "trying" to boot a old IBM PC (NO stinking AT in back of it....this was an original 8086 based PC). Needless to say, that OLD machine would not even power up. What are we still doing with that OLD machine? It's in our Network/PC Services Manager's office in his museum consisting of that PC, a old IBM proprinter and I even think the ex director of the Data Center gave him a piece of original magnetic core memory from our first IBM 360 mainframe! Pretty amazing eh?

    To anwer your question, I think it would be best to setup a direct cable connect with an older machine to do this. Do newer ATX boards even support 5.25" floppy drives?? This way you can setup a script or something to read all of the disks (2 or more if you have that many drives) onto the hard drive then send em over to the newer machine with the CDR. I have a similar issue in that I got some disks I used when I built my 8085A trainer. It has all of the ROM code on them as well as my Senior Project code (although that code would be useless since I don't even have the hardware for the project anymore...I still have the 8085A). These disks were written on a HP 9000 system and I don't even think a PC could read them. Oh well. I don't intend on blitzing the code in the rom and I think if I ask, I could get access to their new rom burning stuff they have now (I bet it's on normal PC's now....). It would be nice to build a little rom burner for my PC and use the ole 8085A to control a Christmas Light display.
    • Do newer ATX boards even support 5.25" floppy drives??
      Yes. It all depends on the floppy cable; you need one with a large connector, and most PCs/motherboards ship with cables that only have the smaller connectors for 3.5" drives. But if you can dig up a cable with the right connectors (or get one at Radio Shack) then it should work.

      The biggest problem you might have is that a lot of 5.25" drives either are fixed as the first floppy drive, or have jumper settings that are long-lost. So you hook up your 5.25" as the first floppy and 3.5" as the second, and then swap them in the BIOS.

      Incidentally, I recently built a 1.2 GHz Athlon box with a 5.25" drive by special request of the customer. It does work, and yes, even Windows 98 and 2000 support it. (Dunno about XP, but I'd presume so since it works with Windows 2000.)

      (This is a little OT, since the orignal poster asked about external drives, but he can always do this and just sit the drive outside of the case somewhere, assuming this isn't supposed to be a permanent solution. Or he could just buy a bigger case.)

      • Well jumpers arent even that much of a problem... Figure you might have a block of six pins with one jumper. 6 choose 2 is what, 6! / 4!2! = 720 / 24 * 2 = 720 / 48 = 15 possibilities. And we musn't forget that only linear combinations are possible so that brings our total down. Then again... if its a block of ten pins then we might have problems: 10 choose 2... 10! / 8!2! = 45 possibilites. Still not bad.

    • Turns out, we didn't but we even resorted to "trying" to boot a old IBM PC (NO stinking AT in back of it....this was an original 8086 based PC)

      Nope - 8088. At 4.77 Mhz.

    There are good chances your data has been corrupted and your quest is merelly a waste of time. Magnetic media will only last a few years. There's no way to tell the exact life expectancy of the media, as it depends, among others, on the conditions if was stored. Here's [scitrav.com] how to store. Temperature should be below 70F and humidity below 70% if you wanted to preserve data for a long time. According to this [google.com], the floppy disks should last from 5 to 10 years.
    • I was rummaging through a fistfull of disks, and I found that my 5.25" disks from several years earlier were in generally better shape than 3.5" disks that were newer. DD disks tend to last longer than HD disks, of course, because the spread isen't as bad.

    • My box of 100 5.25" floppys used in my 286 from '91 till '95 are still 100% readable and useable !

      I cannot say the same about the 3.5" ones. I never used again an 3.5" drive to flash my bios since a brand new 3.5" diskette made me 'happy' with an "BIOS CHECKSUM ERROR" post message.

      The old disks are better - the new ones SUCK ! We want our old trusty floppyes which you could rewrite dozens of times without fear of data loss !
    • it might be ok, i got a load of 5.25" floppies for an Apple //c yesterday, they all date from 1984-5... and so far work fine! maybe Apple DOS is more durable ;)
      • I imagine it also has something to do with the fact that those disks were single sided (some of the disks double sided, with a notch on it near the label, but the Apple //c original drives only read one side at a time) and could only store 140KB per side. I remember drooling over the thought of getting 800KB on a 3.5" floppy. Just think how many Dazzle Draw pictures that would store!

        Anyway, I had similar results with my //c disks a few years back, they all seemed to be in perfect reading order except for one that looked like it had something spilled on it (didn't even try that one).

    First, get a powered 5.25 drive box. So many of these were used for external SCSI CDROM drives, that they can be had for almost nothing. A quick ebay search turned up this beut [ebay.com], which you can "buy now" for $15.00



    Acquire your floppy drive. Once again, ebay makes this easy [ebay.com].



    Remove the CDROM drive and rear SCSI centronics connector from the drive box. Mount the floppy drive in place of the CDROM. Discard CDROM.



    Remove slot cover from PC. Run floppy data cable out the gaping hole and through the gaping hole in the back of the drivebox.



    Done



    Almost all 5.25" drives use a card-edge connector. No floppy cables seem to have these anymore. The easiest way to get the adapter is usually to buy a 3.5" floppy drive "mounting kit" most of which still include the little adapter.



    You will probably have cable-length issues if you want to leave your internal floppy connected at the same time. You can solve this by having a custom cable made, finding an extension cable, or buying a 5.25"/3.5" combo drive (once again, ebay has several) and just leaving the internal drive disconnected (or remove it) for now. Most of the combo drives take an IDC header (as opposed to card-edge), so you won't have to find an adapter or old floppy cable, either.



    This entire adventure will end up costing you roughly $30 and some time. If you are competent with a screwdriver, I would estimate 60 minutes from start to finish once you have all the pieces.



    Have fun.

I haven't been able to test the external floppy for want of a disk, but all other aspects pass IBM's system checks with flying colors. Museum quality, IMO. $29.99 + 5% sales tax.

      (IBM also had/has a much smaller ThinkPad floppy connector, and you might be able to find a 5.25" drive for one of those. But good luck...)
  • I think that the best solution would be to get an old 486 throw in a ISA nic and just install Linux or *BSD on it and just copy the files over.

    Besides after you done you have a PC to play with.
  • I have something that may just fit the bill, although I've never tested it. It is a relic, and it's a ribbon-cable connection, but it has a case and it's own power supply. No brand name on it, and I never could track down any reference on the net to anything like it.

    I picked it up for free, to complement my computer museum. I'd be happy to loan it out however long it's needed, for shipping costs. I'd have to take a little time to hook it up and make sure it really is a PC part and not some other 8-bit accessory, but the connector looked promising.

    Problems with your 5 1/4" floppy? These guys [viagra.com] can help you out!
  • 1) Are you sure your PC can read the old formats? I know nothing of kaypro, but based on personal experience and Apple II emulator FAQ's, PC's can't read Apple II floppies. (Apple tweaked the reading such that a 720k Dos 3.5 floppy held 800k of Apple formatted stuffage)

    2) Do you have the OG computers? Again, based on the Apple II emulator FAQ's, it may be easier just to read the floppies on the original computer and send it out over the serial/parallel ports?
  • After seeing this post, I decided to see what *I* still have kicking around on old floppies. The shoebox of 3.5" disks has the ususal assortment of crap-- Doom1, Windows 3.1, and some disks with drivers on them for hardware that's long extinct.

    In a deep corner of a closet I found the following gem: Leisure Suit Larry 1 and 2, both in the original boxes. Methinks it's time to dig out an old 5.25" drive from the parts box and see if I can get it up and running in a dos emulator. Alas, I may have to follow some of the advice posted elsewhere here to install the drive. Turns out that I've also run out of space on the front of my case.

    Thanks, Slashdot, you've found me a great way to kill time for the evening!

  • Back in the day I had a PCjr (my first computer). When I got it (used) it had an external floppy drive (2nd drive, original drive in the computer) both 360k 5.25". The PCjr floppy controller only supported one drive because it was a supposedly lower-cost version than the PC controller. So the whole kit consisted of (1)a replacement floppy controller, (2)a replacement ribbon cable that ran from the card to the existing internal drive and then out of the case to the back of the (3) external drive case. The external drive case contained a rather large transformer along with I think some diods (extremely basic 120VAC to +12,Earth,Earth,+5 voltages). Also mounted on the circuit board inside of this external case was a ribbon cable that connected to the drive mounted inside the case. The connector for the ribbon cable coming out of the PC to this thing was simply the edge of this board sticking out of the external case a slight bit (with an appropriate hole in the case).

    Anyway, the bottom line is that you can very simply get a longer floppy cable, run it outside the computer case somehow. This kit accomplished this by basically filing down part of the case to leave a slit for the ribbon cable to fit through. You'll probably need to figure out a more creative way.

    Of course you will need to supply power to the drive. Depending on how you can run cables out of the case, well, just run a power cable outside of it too. Or for a more professional solution actually buy an external 5.25" drive case with power supply. I am sure they exist although many of them probably have a SCSI setup. You ought to be able to find a plain one though.

    But lets assume you don't want to do that. If you can get your hands on any parallel port floppy drive then it /should/ be usable as a generic parallel port to floppy adapter. I.e. even if it currently has a 2.88MB 3.5" drive it should work with a 5.25" drive except for the fact that the cable connectors are different (though the signals are the same).

    Oh, one other thing, you mention that some of these disks were not from PCs. Hope you know how to read the filesystem on them. However some disks you just plain won't be able to read because the drive is different (i.e. Apple).

  • Just set your wayback machine to, oh, say 6 years ago, and you'll be able to get one.
