I have a 2Mb 512Ke with a 20M MacBottom, and I've been experiencing
flaky drive behavior since I started using System 4.1.  (I had been
using 3.1.1 for ages, quite reliably, but I foolishly decided to
tempt fate.)  The disc will run for a while, but without warning a
couple of words in the middle of memory will be trashed (presumably
when they are read from the disc).  This also happens with other Macs.
The MacBottom drive diagnostic runs without errors.

I called PCPC and they told me that my problem lay in version 2.7 of
their software.  I sent them $15 for the version 2.9 upgrade.  I hope
to know by late this week or early next week (depending upon the
lightning efficiency of the USPS) whether the new software will
solve my problems.
