On my Amiga 2000 (rev 4.2), both internal drives will spin if either drive is commanded to spin.

The pin was not broken. It is a "key" designed to prevent the plug from being inserted incorrectly. No signals are connected through that pin.

He (and you, I think), should double-check the drive select jumpers, and try the drives jumpered 'both ways'. ie. change 0 to 1, 1 to 0. They seem to be position and address sensitive. I remember having this problem with mine, and fiddled with it until it worked. -larry -- NeXT. The hardware makes it a PC. The software makes it a workstation.

Both floppy drives in my MAST TwinDrive are dead. When I put a floppy in the drive the motor steps back and forth and keeps stepping back and forth until the disk is taken out. Sometimes when I put a disk in I hear a click and the disk spins. It then may work for a while but more often the head starts stepping again, and the I get I requestor that I must put the disk back in drive DFx: Does anyone know why the head steps back and forth? is the drive supposed to spin before the head does anything or is the head supposed to move to a certain place on the disk before the disk spins. thanks, john macdonald
