Re: [vox-tech] In Denial About These Hard Drive Problems



Quoting msimons@moria.simons-clan.com (msimons@moria.simons-clan.com):

Just to clarify, I absolutely agreed with that recommendation.  I was
just saying that there have been lots of _other_ IBM Deskstar and
Ultrastar models, not members of those series, that have been just fine.

I can't speak to Win2k, having little relevant experience.  However
"reconfiguring" for the Linux side could be nothing more that migrating
and unpacking a tarball of /etc.

Yeah, good points.  I usually aim to get things off at the _first_ signs 
of drive trouble -- which from evidence cited would have been a lot earlier.

Doing a "dd" of the partition and piping it over ssh to another box
might have been useful.

Really bad juju.  I think I'd have called in an exorcist.
