Thanks for the info. I guess for this test I have to find a replacement
high-denisty drive. The drives in the unit are, apparently, high-density
drives but the disks are 360k disks made with another working system.

Hello, all:
I'm trying to get my "new" Micromint SB180 to work with
the floppy drives
that came with it. I've been given two sets of disks, both of which were
made on a known-working system but which produce read errors on mine.
The drives pass the internal disgnostics that are in the
SB180 ROM, but I
want to eliminate the drive from the problem by swapping another in. It
appears to use standard 5.25" 1/2-height PC drives except that the "old"
drive has a head-load solenoid while the new one doesn't.
The model number of the "old" drive is FD55F-03-U and the
model number of
the "new" drive is FD55BV-36-U. There are differences in the jumper
designations between the models so I can't readily map the settings.
Can anyone help with this? Thanks.
Rich, the 55F is a 96tpi drive while the 55BV is 48tpi. That
difference is likely the cause of your problem.
