Hard disks will die. Eventually it will happen.
I've been in Tech Support for awhile but lately I've encountered a problem that is beginning to worry me.
I have 4 computers networked at home all running Windows XP. As part of a monthly routine I backup all systems and check h/d to see if they need defrag.
A month ago I ran defrag on one of my machines and within 2 days the hard drive completely crashed. Last week another of my machines was defragmented and within a couple of days the h/d crashed as well.
All systems have the latest antivirus, spyware removers and all updates, so I am ruling out virus / spyware.
