    Thanks a lot for the advice. These are Western Digital WD1200JB drives.
    I have 2 running with software RAID1. I bought them last September and
    have a hard time believing they will crash on me. Software error is much
    more likely. But I'm so new to radio that I worried about the 45 watt
    Kenwood zorching my machine.

    I reinstalled Red Hat Linux and formatted the disks several days ago,
    before posting this. I hadn't noticed any messages with the syntax
    'unrecoverable error hdx' and the drives (still in a software RAID1
    configuration) seem to be performing well as they always had up until
    last week.

    Another suspect on my list is my Ximian Evolution email client. I had
    accumulated about 30,000 emails, maybe more, at the time of the crash
    and when it did crash I was using Evolution. Maybe it was really
    Evolution's fault?

    73,
