Hi
I have a machine with a 77711501 floppy drive and it's bad.. I have
tried 3 different 360k drives. I tried to find specs on it but so far have
not.
What is the difference between that drive and a
77711800 used in a PC
The computer just says there is a drive error. I'm using the same jumper
settings on both. I have also tried a Teac fd-55bv.
Is it a 320k drive ??
There ain't no difference.
320K drive and 360K drive are the same drive.
There is a way that it would be possible to build a drive that could do
320K, but not be able to do 360K, but nobody has done so yet.
Boot something other than WINDOZE. "Drive error" is not specific enough.
And for the rest of the story .....................
This is on a MicroStar machine that runs StarDos. I know nothing about this
but from recent posts I decided to drag one of them down and look into it a
little further. This machine I have running is a Micro Five 1000 with a IMI
10 meg HD. It has a boot menu and back up Menu. It will still boot and
will make its own formatted floppies and back itself up with out much
problems. If I try to read one of the floppies with Image disk or Anadisk
they fail. It tried with both 360 and 1.2 meg drives. I would guess that
the drive in the machine is off enough to cause these problems . If I
install another floppy drive, the System picks up something and errors. So
there must be some other signal or ??? coming from the drive. The
machine date is in the 84 -85 range
The straps on the drive (M 4 x 3 2 1 H) are set with M and 1 jumpered
