I've just had another seagate drive die on me.
This time it was a 320gb SATA2 one, so pretty new. One of the chips on it died and there was an awesome smell.
We've had so many seagate drives die now it is not funny (2 this week). I've personally had about 5 this year.
Anyway as I've said before do not buy seagate drives, they just don't work.
We've been using Samsung drives, they're cheaper and work better than seagate drives.
Last week we upgraded housefiles to 4x750gb HDDs in Raid 5.
