[comp.sys.mac.hardware] Diagnostics for Floppy Drive

c3ar@zaphod.uchicago.edu (Walter C3arlip) (03/11/90)

(1) Does anyone out there have a simple diagnostic program and/or exerciser for
a floppy drive?  My hard drive came with a nice program that would run for
ever writing to sectors and reading them, counting errors along the way.
I'd like the same for testing a floppy drive.

(2) I have an old 400K floppy drive that had what I've been told is a very
common problem: its grease gummed up making it unable to eject disks. After
application of a bit of WD-40, the drive now ejects disks, but has another
problem.  It now refuses to initialize disks.  It will read and write to
disks fine, but fails to initialize (usually failing in the verification
stage before writing the directory).  Has anyone seen this problem?  Any
suggestions on how to fix it?

Thanks,

--Walter

I'd simply try a disk drive cleaning kit... Basically, they consist of a 
phony disk and some cleaning fluid that you use.  That might do the trick.
