Well, in nearly 20 years of running computers at home, I've had about
3 or 4 fail on me. All SCSI strangely enough (but that's just cause

quite unlikely to hear any clicking:
1. Sys admins dont usually sit in the machine room
2. Even if they did, they still wouldnt hear the clicking due to the
general noise in a machine room (air-co, fans, etc.)
First thing you know is usually that the RAID controller has kicked
the disk and is flashing the LEDs for the drive, or you get an email
from mdadm or compaq's smartarrayd to say a disk had died.
If you believe disks are ultra-reliable, you simply have not worked
