this?  Your hard drive is failing. Often, but not always,
uncorrectable errors are preceeded by correctable errors. Once
you start seeing uncorrectable errors on an IDE disk, either the
disk has so many bad blocks that its relocation table has filled
up - or the blocks went bad with no warning, so they couldn't be
read to be relocated.  The former case is the most likely. Just
be thankful that you're running a unix system, where you
actually get to _see_ these errors - in Windows, the OS would
just keep retrying, and never tell you there's a problem. You'd
find out when your drive was so far gone that programs failed or
it wouldn't boot...  David Maxwell,| --> An organization gets
