Trying to install 5.25 floppy

Teac / Fd-55gfr 149-u
February 21, 2009 at 03:23:41
Specs: Windows Vista, Intel Duo Core 3.0 GHz/ 8GB ram
I've only just completed my first build, but in the process, I decided I'd like to back up some very old files from my Atari 800XL days.
I bought a Teac FD-55GFR 149-U 5.25 Floppy drive and cable, and to the best of my knowledge, hooked the cable and power correctly. I also made sure to enable the drive in BIOS. Vista says the "device is working properly", but on powering up the LED does NOT come on. I'm requested to insert a disk, and when I do, the motor cycles once and then locks into place, but nothing else. I've been reading some of the threads on jumpers, but still do not understand their purpose, what they even are exactly, or if that may be my problem.

Any help would be appreciated - Thanks

Floppy drives don't have jumpers. All you have to do is connect them to the cable, configure the BIOS & go. If you have two floppy drives on the same cable, the one connected to the end plug will be the "A" drive & the one connected to the center plug will be the "B" drive. If you only have one drive, connect it to the end plug & it will be the "A" drive. Then go into the BIOS & set "A" to 5.25"/1.2MB. Make sure you have the ribbon cable plugged in correctly...the red stripe should be on the side closest to the power connector.

I sure hope you didn't pay much for the drive...a couple of bucks maybe?

I don't know anything about Atari floppies but I am guessing that Vista can't read them without help. If you have a BLANK 5.25 floppy insert it and try writing to it. That will determine if the drive is configured right and working.

Jam - sorry but I must disagree with your comments on this one.

a) you say one should not need to change straps on a floppy drive. However, according to the manual (which I have), this drive has a number of straps, which if second hand, could have been moved in the past.

b) the red stripe on the ribbon cable signifies the pin 1 side.
I have seen pin 1 in just about every conceviable position on floppy drives.

Regards - Mike

Othehill has a good point, I would test with known good pc floppies before trying to read Atari ones.

I would like more details about the cable or cables that came with this unit.

Normally the data (ribbon) cable connector is moulded such that it can only fit one way on to the drive. Am not sure about the mobo end though.

Good Luck - Keep us posted

Both the 3.5" & 5.25 connectors could be reversed as can the motherboard end. As was mentioned the red stripe is #1 wire.

Connecting backward was a very common problem back in the day. Usually results in the drive light staying on and of course the drive not working.

Most cables had 5 connectors on them. One for MBoard and 2 each for each flavor of drive. My first PC was equipped with both types.

I still have a crapload of the old floppy cables with CE connectors OtheHill describes. Also keep one machine around with a working 5.25" floppy for the occasional boot floppy etc. I need to make.

Like Mike said, some 5.25" drives did in fact use jumpers to set the drive as A or B or set the rotational speed.

Don't recall the model number but both my 360
Mb drives from an old 286 use jumpers for drive configuration.

To jam, no I paid exactly 2 dollars for both the drive and its cable.

The cable can only fit onto the drive one way - fairly obvious, and the other end without the twist I assume was meant for the mobo, especially since there is one corresponding pin out on both cable and FDD that match.

As to the jumpers, I found one relavent item that refers directly to it:

I imagine I will have to read through this about a dozen times before it makes much sense.

SkipCox - Visited the included link and the green jumpers are in the same locations FG, D1 and DC. Not sure what the bottom red circle around the pins going to the cable signifies. Says only the green jumpers were applied with this revision, but why are the other color jumpers pictured?

Sorry, lots of questions and although I anticipated some issues on the software end, I didn't think I'd be getting so deep into the hardware portion.

Thanks for all your input.

Here's a good pic of the cable.

The twist is to denote the "A" drive..."B" drive goes on a connector without the twist.

I'll dig around for an old book to see what jumpers are configured for "A" and "B". I remember "PC Upgrade and Maintenance" books from the early to mid '90's devoting an entire chapter to configuring 5.25" floppy drives.

My cable has only the one for A and B. And since I am only installing the 5.25 floppy, it is going to the B. BIOS was told to use A...I don't think it offered an option for B, but I will have to look.

Help with the jumper positions is appreciated.

If your only installing a single floppy drive, it needs to be the A: drive. There is no reason to have a B: drive if there's no A: drive. The flat 34 conductor ribbon cable used for connecting floppy drives to the motherboard will have one of the connectors where an inside section of the cable has been split apart and twisted over just before going in to the connector. That is the connector for the A: drive.

It's driving me crazy...I've tried several jumper configurations suggestions I've found at other sites, have at least had the drive "wake up" while Windows was loading via the LED turning on. But Vista still insists that I haven't inserted a disk.

Have you tried a blank floppy? Is the floppy drive showing in Vista?

Floppy does show up in Vista, but here's the showed up in Vista even after I had temporarily removed it, but left it configured in BIOS. Needless, I don't trust too much what the OS is saying, I'm just looking for the drive to work. All the floppies I have are 20+ year variety, so perhaps I get my hands on some newer ones and see if they're recognized.

As was stated up at the top of this thread Atari floppies are probably not going to be readable. Not by Vista anyway. Does the drive activate when you insert a floppy?

If you want to test it, place a tab of masking tape over the notches on the top of the floppy. Then attempt to write to the drive. The tape will stop any writing from happening but you should get a message that the disk is locked.

I wasn't going to try reading them directly. Rather I intended on just copying the data to my drive and using my Atari emulator to open them later (I was assuming they were in the .atr file extension like the game files I acquired earlier). The drive does activate when I stick in a disk, but looking at the mechanism it would activate for any disk shaped item I put in. It spins while the door arm is up, then locks into place when I close it.

The drive is currently out of my's too big to fit, so I've been running it connected with the computer side off. I place it in such a way that the drive is free to spin.

Well, I gave you a method to verify the drive is functional.

I have a 5.25" TEAC floppy drive in my computer, when I select it from windows without any floppy disk in it, the LED will light up and you can hear the head seek function clicking around before Windows pops up an error message stating that the B: drive is not accessible, "the drive is not ready". If you see that kind of activity, then your floppy drive is properly installed.

If all you have is old 5.25" floppy disks which were created using an Atari 800XL with an Atari floppy drive, it is possible that your TEAC PC floppy drive will not be able to read them. Atari floppy drives were not made to PC standards, very close in many ways, but not the same. If your goal is to try and recover the data on these "ancient artifacts of computer history", you should spend some time studying the issue. You could damage the data on the disks by just trying to read them from a Windows PC using a standard PC floppy drive.

I knew there were ways using old Atari 1050 drives with adapters/software available to hook it up, but I assumed an old internal floppy drive would have functioned well enough to just pull off data. I will read further.

If all this time you have been running it outside of your computer, it may need earthing.


a) Clean out drive, by blowing with a hairdryer set to cold and maximum blast.
Check if any balls of fluff remain and remove carefully.

b) clean read/write heads with a *bent* cotton bud/Q-tip dipped in isopropyl alcahol (the chemical supplied with cd/dvd cleaning kits).

c) check for bent pins in the cable connector socket(s).

d) if led never lights on unit, you need to try another cable.

e) check bios - there may be one entry for drive type and on another page one to enable drive.

Good Luck - Keep us posted.

Have moved beyond hardware.

I picked up an old UFS case with Windows ME for $15. I set the factory default jumper positions and used the cable to set up both floppy drives. The drive is recognized and tries reading one of the floppies. As of now the issue is now software. Windows is asking if I'd like to format the disk.

To play it safe, I've been using a disk with games I already have as .atr files. I know there's freeware with the ability to access information using the orignal Atari 1050 drive, but will it work in my application? I'm going to try.
