The cables for my floppy drives got disconnected.
I have two drives A and B. Can someone advise the correct way to re-connect the cables. When I boot up the computer the screen shows the floppies and the cmos is set up, but the floppy is not accessible after boot.

Look at the cable to determine where the seven or so wires are crossed. The connector closest to the switched wires will be for Drive A:, the next set of connectors will be for Drive B:, and the last connector will attach to the motherboard or controller card.

I attached the cables as you suggested. However,
the lights come on in the front of the computer on the floppies and stay on and I still can't access the drives.

If the lights stay on, you have the cable on backwards. Normally, the red wire on the cable indicates Pin 1, and usually goes toward the power adapter.

On 3½ floppy drives Pin 1 is almost always away from the power adapter.

TEAC and NEC diskette drives the Pin 1 is located closest to the power adapter, but other models of floppies can be different.

Abe and others
Thanks for all your help. After many tries and much frustation I finally got my floppies to work.
On my computer the cables are reversed.
Thanks Again

Similar prob...
I need jumper settings for 5.25 floppies. The
jumpers will set the drive's position (A or B)
and possibly set other things like terminating
resistors (not good on B:!), media sense by
logic board or controller, motor control, disk
change signal.........
I have 5 mini-floppies and two are straight
forward and well labeled- I can't use the others
'till I learn thier settings. Newtronics, Chinon
and Teac. Also, regarding cabling-- twisting wires 10-16
will switch the drive's designation from A: to
B: and vice versa. 3.5's are usually hard-wired
for B: and "twisted" to A:-)
Somewhere on the net there *must* be a page about
Also, I could use a drive that'll take FORMAT's
/T and /N switches, any ideas welcome.

I've a similar problem. But I've already checked the cables, the jumpers for drive A and B, Disabled the onboard interface and put a new interface offboard, I've changed the cables, the drives, the disks, I've done everything possible to me. I'd thought the problem was the motherboard(VIA-501,P100), 'cause it's very old, but with the change of interface I defeat this option. What hell do I do? Thank you!!!

I formatted the C: drive. Now I only get a prompt. Tried to use a boot disk, but computer does not recognize either the A or D drive. Says it cannot read A and that D is an invalid drive.

Julie you should have started a new thread for this.

Anyway possibly the floppy your using is faulty. I have hundreds of old floppies I gathered up over the years and find there is a fairly high rate of failure (on these old ones).

Or after trying several bootable floppies and sure that the ribbon cable and power is connected OK it probably is that the drive failed (or remote possibility the cable).

Here is my favorite place for getting (and making) boot disks Here
