We have been having problems with our RA81s on our VAX780s , and we have
already ordered another one.  We had been seeing "hard errors" at a reasonably
low rate, but finally we ended up trashing an entire disk.  When the RA81 was
the root device, we were crashing the system as much as two or three times a
day.  When we moved the root to another device, the problem was reduced greatly.
I had heard something about a bug in the driver, so we contacted Berkeley,
they sent us a new driver, but it scribbled all over the disk.

Does anyone know about a REALLY fixed driver?  DEC diagnostics seems to think
that the problem is software, not hardware.  Besides, the problem occurs on
several machines with RA81s, and none of our machines running VMS have had
problems with RA81s.

This is really important, please respond to Andrea Akerib (decvax!genrad!andrea)
