[comp.sys.ibm.pc.hardware] 1.2meg drive problem

A 1.2meg drive I'm installing has a problem with changing disks.  It
seems that it can't tell when you've swapped disks:
"dir" reveals the same directory no matter what disk is in 
the drive.  I didn't do any writing to the disk because I worried that
the original disk's FAT info would overwrite the new disk.

I've heard of this problem with 720k drives and the solution involved
setting a jumper, is this the same problem?  Anybody know what jumper
I should set.  When I took off the cover, no jumpers were set at all.

oh yeah, the computer is an original IBM 512k AT with a Western Digital
(16 bit) MFM/floppy controller.  The batteries for the CMOS had been removed
as well (just in case that's important)

Thanks.
