Anna,
Has your machine been opened or had anything changed inside
recently ? Or did this show
up only after the OS change ? I wonder if you have a bad SCSI ribbon
cable . Or possibly dirty SCSI connectors.
You might try wiggling the ribbon cable gently at both ends to see if
anything changes. Or , with the power unplugged, pull the cable carefully
from the machine and using electronic contact cleaner thoroughly on
the connectors and pins at both ends. You might also want to pull the
CPU card and clean it's contact strip too.
Anyway , hardware problems sometimes seem like software problems.
Best regards,
W.A. D'Alessio
