<whine>But it was less than a year old... I feel like such an ass for buying this $120 thing that was essentially disposable.</whine>
It's still under warranty, yes? If it's under warranty, no sweat. Just keep killing them...and don't expect them to be reliable. What I always do with disks is that I check the manufacturer warranty, then subject it to gruelling use in an attempt to kill it before the deadline. Then I bitch at them and get them to send a non-broken one, rinse, repeat. In the old days I could recycle a disk like 3-4 times this way before they declared that model to be out of stock and gave me a better one to kill. Lately they've started to catch wise to this, though.
Errr... Pescado, what do you mean by RAID? Another acronym?
Redundant Array Of Insuperior Disks, mostly. There are some people who argue that the I is "Inexpensive", but I wouldn't call a $120 disk inexpensive, especially when it's being used as an expendable unit.
