Hello OSF managers,

        I am running into a very odd happening on a box. Maybe you can help.
following after this description is a sample error I am getting when I try and
access this disk (my current system disk) ... we noticed the problem yesterday
after i upgraded the machine to 96 MB ram. One of the developers tried to use
vi on the machine and got the following message:

Bus Error (core dump)

My question is ... has anyone ran into this problem?

Is it a drive going bad?

Most all the rest of the stuff on the drive runs. I have had trouble with uerf
also.

I have checked all the cables to make sure they are seated properly and even
switched cables going to this drive.
  
My current system is a DEC 3000 model 400 at firmware 6.0 and running OSF/1 3.2
(rev 214)

Thanks in advance for any help.
