Nah, I keep the crazy drive around as an interesting test case. Fun to
see what happens when I connect to a RAID card; very informative about
how thorough the card's investigation of the drive is.

Well, what I was pointing out was that all the 15K drives used to come
out of this plant in Singapore, which is also where their good consumer
drives used to come from too during the 2003-2007ish period where all
their products were excellent. Then they moved the consumer production
to this new location in Thailand, and all of the drives from there have
been total junk. And as of August they closed the original plant, which
had still been making the enterprise drives, altogether. So now you can
expect the 15K drives to come from the same known source of garbage
drives as everything else they've made recently, rather than the old,
reliable plant.
I recall the Singapore plant sucked for a while when it got started in
the mid 90's too, so maybe this Thailand one will eventually get their
issues sorted out. It seems like you can't just move a hard drive plant
somewhere and have the new one work without a couple of years of
practice first, I keep seeing this pattern repeat.
