   Yes, we've seen the same thing here on MACs running System 7.0.1 on a
MacInstor HD even without Genera loaded. A co-worker of mine purchased a
MacInstor for his MacII at home and it trashed his disk a number of times
after loading System 7.0.1.  He thought System 7.0 was the problem but
finally called the company that produced the MacInstor and they had a patch
that fixed the problem.  When we got some MacInstor's on some of our
MacIvories at work, we were suprised it came with version 7.0.1 without
the patch.  We quickly loaded the patch and haven't experienced any 
problems since.
