Subject: Re: data parity error


Thanks for the help. I was wondering, this error didn't start happening until
I installed the scsi drive. Now the message says that the scsi drive is
merely reporting the problem. Is it possible that the controler is wrong and
that it IS causing the error; or is it that nothing else reports such things?

One other thing: the controler that is reporting this is 'scsi1'. I only have
one scsi device in my system.... unless you want to consider the cdroms as
scsi devices. If that is so then I have 3. Or is scsi1 the first device as
opposed to scsi0?
