I had quite bad experience with Seagate disks of series Medalist (IDE),
Hawk and Barracuda. Any failures for any taste: bed blocks developed
over time, disks just dying, disks occasionally self-erasing the
boot sector, disks agreeing to start only after 15 minutes in front
of air conditioning cold air duct. The worst case was when both
disks in a mirror developed bad blocks with half an hour interval.
Luckily the bad block on the second disk happened within the Oracle's
TEMP tablespace, so the actual data were not lost.
Of 40 IDE medalist disks 1/3 developed various kinds of problems
within a year.
