Check the floppy disk cable and the drive select jumpers on the drive.
Generally, the drive jumpers are set for disk 1 (of 0 - 3) and the
floppy disk cable has a twist in it (don't confuse it with the MFM HD
cable that also has a twist) with the drive at the end of the twist
being the A drive. But there were exceptions :).

I recently recieved a Tandy 1000 HX in beat up condition that I gutted to upgrade my mint
condition version. I removed the memory upgrade card and installed it into my stock unit
to give 640K memory. I installed one of the 3.5" drives from the beat up unit into my
machine (2 drives there now) but the computer doesnt recognise it. Is there a jumper on
the unit or software that is needed to setup the 2nd 3.5" internal drive? I connected
the gutted unit up and it still tries to find the 2nd drive I removed so its not
autodetected.
