[comp.sys.amiga.hardware] Flakey Floppy part III and other wierdness

C506634@UMCVMB.MISSOURI.EDU (Eric Edwards) (11/16/90)

For those who don't remember my earlier posts: Flakey Floppy and Flakey
Floppy, the saga continues.  A little recap.

Since about mid august I've had serious problems with my floppy drives.
They would read fine but would quickly corrupt a disk if you wrote to.
Note that ALL the drives do this: internal, old pioneer, and brand new supra.

Just before I completely lost my sanity, I found a wonderfull program called
TrackSalve.  It has an option to verify all writes and retry up to two times.
If the third write fails to verify,  a requestor pops up to try again.

This solved the problem for a while.  Times when the drives failed to write
in three attempts were very rare.

Unfortunately, my drives have gotten steadily worse.  I can no longer expect
that deleteing all the files on a disk or copying many files will not pop up
the requestor at least once, if not several times.

I have noticed some patterns.  The chance of an error is dependent, not on the
total access but their frequency.  Downloading the contents of an entire disk
will work just fine.  Deleting these files with delete * all will results in an
error if there eare more than about a dozen of them.  Operating on two disks
at once is virtually unusuable becuase of the number of errors.

The chance of error seems to have some relation to the "distance".  df1: is
worse than df0: and df2: is the worst of all.

Another thing happend recently that may be totally unrelated but I'll mention
it anyway.  My "n" key stopped working.  "n" and "N" output nothing.  Alt-N
did something though.  I rebooted and, as expected, the n key worked.  But
the "y" key didn't!

Has  anyone out there heard of anything remotely like this problem?
Or better yet, have a suggestion for fixing it?
