Magnetic Wobbles Cause Hard Drive Failure 276
An anonymous reader writes "According to this report by IT PRO, scientists working at the University of California have discovered the main reason of hard drive failure. According to researchers, some materials used in hard drives are better at damping spin precession than others. Spin precession of magnetic material effects its neighbors' polarity and this can spread and cause sections of hard drives to spontaneously change polarity and lose data. This is known as a magnetic avalanche. So next time Windows fails to start, you'll know why!"

Pretty sure that's not the main reason. :-(

I guess the likelihood of an undetected media failure when you have 2 sets of parity must be very low.
For those on RAID-5: remember to run periodic Verify processes and make frequent backups!

You're also ignoring that every OS X system will be running from a hard drive, so it's as much an OS X issue. And a *BSD one, a Solaris one, and every other OS.
Mindless Windows bashing just is not cool, and only serves to lessen the impact of genuine gripes.
