internal floppy to external

December 1, 2010 at 10:25:56
Specs: DOS 6.22, 8MHz/640K RAM
How can i convert an internal floppy drive to an external? The drive uses IDE and i need to connect it through a parallel printer port. I plan to use it with a toshiba t3100/20 so any tips on how to make it work would be appreciated.

"The drive uses IDE" Unless you have a zip drive it doesn't connect to IDE. At any rate why do you need to convert it to anything? Explain your problem. Standard floppy cables are very similar looking to IDE cables. Are you sure you need IDE?

I found the link below interesting.

I may be mistaken. I know that they use sata or something else and i may have heard that they use IDE. I need to connect through a parallel printer port because the laptop i want to connect it to only has a printer port. I think the floppy in the laptop doesn't work so i thought i could install stuff from an external floppy. Also does anyone know how to open the toshiba t3100/20.

The link I included spoke of an optional 5.25 floppy drive that connected to the parallel printer port. That said, I don't think you can do what you want to do. The floppy drive may be replaceable in the Toshiba unit you listed. Quite possible it may be a standard floppy drive or a half height.

One problem would be powering the floppy. The parallel port doesn't supply power to a printer. Just a bidirectional parallel connection. Not sure if you overcame the power issue if it could be done or not. The internal floppy you may have in the Toshiba is probably a double density 720Kb drive. That would be a hard unit to find. You may be able to tell something if there is a BIOS you can boot into.

Maybe someone even older than me will come along with some additional info.

Also is it possible for a pc to emulate a 720K floppy so the laptop would just think my pc is a floppy.

With a 286 I am out of my realm. I started out with apple clones and 486s. Seems to me the simple solution would be to try getting your internal floppy working. What is wrong with it? Does it show up anywhere?

I don't remember the exact error but i doesn't floppy discs, and loops when i try to format. The floppys are formated to 720K and a computer with win xp reads it fine.

I did have an old 5 inch floppy in an external case that I could hook up to a parallel port. It was an IBM product. The drive was a common drive but the parallel adapter and it's driver were from IBM. It has been so long I doubt I can remember if one could boot from it without special IBM equipment.

Unless you can find one in some online place you will not find one new.

Consider mounting a shared drive on some other computer that can support a usb floppy or internal floppy.

They are not ide by the way.

In DOS setup you can choose 720K/1.2M drive. Would the laptop work with a 1.44 drive if i would set it as 720./1.2 and use 720K floppys?

The machine is a 286. Ain't gonna run XP on there.

Many 3 1/2 floppy drives will read both DD and HD floppies. Why do you need the floppy drive anyway. What are you going to use the laptop for?

If it is a 286 I doubt it would support a 3 1/2. I think you needed a late model 286 or 386 and above.

Yep, no way to run a virtual floppy in a 286. It would still support a lan floppy or shared folder. See barts network disk.

RE # 9. You can't use a 1.44 and tell the bios it's a 720 K. Normally a 286 can handle all four types--360 k, 720 K, 1.2 and 1.44--although your particular bios may not allow it.

Even if you found a way to connect a floppy drive via parallel you'd still have to load drivers before it'd work. And how are you gonna do that if you don't have a drive with which to install them?

Just fix the floppy drive. Or maybe it just needs a good cleaning.

"Just fix the floppy drive."

Does it spin for at least a short time when you insert a floppy disk into it? It MUST spin.
If it doesn't, remove it, open it up, and see if it will spin after you have fiddled with it.

If it DOES spin.......

"Or maybe it just needs a good cleaning."

Try a standard floppy drive head cleaning diskette in it, without or with cleaning fluid on it's "disk" (e.g. isopropyl (rubbing) alcohol, or methyl (wood) alcohol, or ethyl (drinkable) alcohol).

T3100 series
http://www.old-computers.com/museum...

Excerpts:

There were five models (That I am aware of) in the T3100 series: The base T3100 (Which I shall discuss here), the T3100/20, the T3100e, The T3100e/40 and the T3100SX.

The base T3100, released in 1986, consisted of an 80286 CPU running at 8MHz, but could be slowed to 4.77MHz using a keyboard shortcut. It also had 640KB system memory, which could be upgraded to 2.6MB. It shipped with MS-DOS 3.2.

Storage included a standard 3.5" 720KB floppy diskette drive, and an internal 10MB hard disk drive. An optional external 5.25" floppy diskette drive could also be connected through the parallel/printer port. The T3100 also had a special optional "floppy link" cable, which allowed the T3100 to connect to and use the floppy drive on an IBM desktop system.

Although portable for the time, the T3100 is a beast in comparison to today's portability standards. It was 12.2" wide, 14.2" long and 3.1" thick, and it weighed a hefty 15 pounds, quite a burden to carry around. ....the T3100 was simply just a luggable computer. Except for the T3100SX, it had no internal battery, thus it required access to an AC outlet to operate.

Quick info about the other T3100 models:
• The T3100/20 was essentially the same as the base T3100, except it had a larger hard disk drive (20MB instead of 10MB).
• The T3100e had a 12MHz 80286 CPU, 1MB RAM and a 20MB hard disk drive.
• The T3100e/40 was the same as the T3100e, but with a larger 40MB hard disk drive.
• The T3100SX had a 16MHz i386SX CPU, 1MB RAM and a 40MB or 80MB hard disk drive, and also included an
internal rechargeable battery for true portability.

T3100 Bios
or
T3100 Bios Setup

To gain access to the T3100e BIOS, hold down the [Fn] key while it is booting up. After the memory check is finished, there will be two short beeps. Press [F1] to get into the BIOS.

That should work for your T3100/20 too !

The floppy drive makes some noise but i don't think its spining. i tried opening it but after i take out all the screws it still doesn't open. It semms to be stuck on something near the top of the keyboard. I tried googling but didn't find anything. Could there be a latch there or something like that?

It's probably plugged into an internal connector at it's rear - you probably need to release it from that.

Did you try ejecting it's tray then gently pulling and wiggling it with the tray ?

You could try searching for something such as : T3100 manual
but it's not likely your going to find a manual - it's about 23 years old.

Or search for: "remove floppy drive" T3100 with or without the quotes.

Or contact one of those web sites I found the floppy drive for it listed for sale.

Wow!
Do you have any other old treasures ?

PC-PA7367E Floppy Link to 5.25 desktop diskette drive (no longer manufactured)
(just the cable ?)

That would be very useful to Dariuz, if he has an external 360kb floppy drive with a 25 pin connector that is compatible with it, which I doubt, or if you also have the PC-PA7225U 360kb drive that goes with it, or another floppy drive it will work with.

When I searched on the web for one of either of those for sale, I found nothing.

On the other hand, if he's too cheap to buy a $7 manual for this laptop, he may not like having to pay to have it / those shipped to him either, even if you're giving it / them away.

Do you know what he needs to do to remove his floppy drive and t-shoot it too ?
