Hard Drive Failure?

I posted something similar to this in general, but didn't get any responses..

How often do (EIDE) harddrives fail? What's usually the cause? How often can they be repaired? And how often can the data be saved?

I've had my computer running 24/7 for almost three years, and I've never once had a problem with the harddrive.. is this normal? have I been lucky? About average?

Thanks.
 
Hard disks have moving parts, anything with moving parts will eventually fail. You'd have to find out from the manufacture what the MTBF (mean time between failures) is for each model drive. Depending on what happened and how far gone it is (they don't usually just stop working) you can get the data off, or you can pay (out the ass) to get the data recovered by a professional.

IDE drives are generally less reliable compared to SCSI ones, but neither fail enough to make that a purchasing decision.

For instance Seagate's Barracuda (ATA 80G) has a MTBF of 600,000 hours running time and their Cheetah (SCSI160 74G) has a MTBF of 1,200,000 hours running.
 
600,000 hours divided by 24 = 25,000 days.

25,000 days divided by 365 = 68.5 years.

How do they work that out?

Seems the SCSI should last 137 years... damn impressive, they had SCSI drives back in the nineteen hundreds and they have been testing them since!!
