[that was my quote, by the way, not Ted's :-)]

SCSI is a totally different thing, but we're talking about IDE here. With
IDE consistant errors on certain blocks are almost guaranteed to be
physical disk errors - I have yet to see a counter-example.

Of course, nobody says you should scrap the drive just because the linux
kernel happens to spit out some IDE errors. :-) It is however a pretty
good sign that something is wrong; as Ted said, it is almost always the
first sign that the drive is aproaching its life-end. Replacing it is the
sensible thing to do if you value your data on it.
