DOS Command for coppying from A to B Drive

  Ex plorer 20:57 25 Mar 06

Hi I have rigged an old PC up to coppy from Floppy drive A to a second drive B.
A is the main drive as this is where the twist in the cable was left.
The PC will only boot from A:
Both A and B are selected in the BIOS
At the moment I have DOS 3 installed.

If I load a disk into A: Drive what command do I use to copy to B drive?
I have tried a few commands just guessing and the A and B drives seem to talk to each other by the A drive light coming on and B drive clicking and light coming on then goes out and back to A drive. As if it is waiting for a second command.

I Had a look on the net for some ideas or maybe someone here can shed a bit of light on what to do.
Any suggestions and I will give it a try in the morning.

If you want to copy a whole disk ar once, you should use

diskcopy a: b: /V

this produces a duplicate disk, and verifies the target disk.

PS - you don't need two drives to duplicate a floppy disk

diskcopy a: a:

will do the job, and prompt you to change the disk in the drive when required.
