I've got the same ST238 you do, Bob, and the same problems.  I wanted to have
my dealer fix it, however I just don't have the time he wanted to spend
looking at it, so I've suffered with it for a while.  After a period, you
get used to it.  I usually leave my system on all the time (which is really
better anyhow), however if it gets real hot during the day, I'll turn it
off.  I agree it's related to heat; I've proven it.

Recently, however, I ran DiskOptimizer on my disk and it rearranged the
files enough that the majority of the 'boot-up-required' files aren't in
the first few hundred sectors (where the controller thinks the bad sectors
are).  By the time that I get around to touching the files in that first
area, it's usually okay.  Interesting test: when you get booted up, run a
utility like SCAV30 on your disk as soon as possible.  It will let you know
the sectors where you shouldn't place data.

If you find a better solution - LET ME KNOW!

thanks
