I currently have 2 5" floppy drives
Panasonic JV-475-3AGJ
NEC 1157C
Latter one works @ my K6-2 system as drive B pretty nicely. So drive overall should be OK.
I wanted to migrate it to newer system PL5P -- Dore2Duo, 4G ram and latest Linux Mint .
WHY - to have all linux goodies (dd, sftp etc.) Anyway, here comes weirdness.
Linux correctly detects the floppy. I jumpered it as floppy A, because mobo BIOS only accepts one floppy drive. Dirve is set as 5" 1.2 at BIOS.
Now -- when I try to mount it, it starts spinning and then gives error message - no valid block device.
If I HOT SWAP between NEC and Pana it mounts and reads direcotry listing. Still some errors but something.
BOTH drives refuse to move head. 12V is ok. NEC is tested on other rig under win and FreeDOS and works OK.
Tried both straight and twisted cable, straight does not even start spinning.
3.5 inch floppy, pn the same rig works and reads OK. Any suggestions? Where can "move head" signals be stuck?
