noone has yet mentioned S.M.A.R.T. yet. After I went through a stint of loosing 2 hd's in a week's time (due to powersupply problems) I looked into things and found smartctl, which monitors the smart status of drives and can even be setup to email you when it encounters a problem. According to manufacturers warranty's upon a SMART pre-fail warning you are allowed to, if the drive is still under warranty, get a replacement. I've done this a few times since, once with a Maxtor SCSI drive and once with a seagate ATA drive. I suggest paying the extra shipping cost to receive the new drive so you can copy your data over. Keep an eye on the drive. I'll usually put it into a ro mount and if gets really bad I unplug power to it until I get a new drive. This is a good way to circumvent any possible issues, but for a sudden failure, backup is key.
