When is it time to replace a hard drive?
Posted on 2007-08-12
In October last year some of the startup files on a Windows XP PC were corrupted and the computer was caught in a continual reboot loop. I ran the Seagate disk utility (Seatools) and this revealed 56 cable test errors, so I replaced the IDE cable. I booted the PC up using the XP CD and performed a System Restore from within the Recovery Console. This got the PC up and running again.
The same PC got caught up in a continual reboot loop again. At first I couldn't even communicate with the hard drive, even after removing it and attaching it to another PC using an IDE to USB adaptor and PSU. Ended up returning it to the PC and amazingly (to me) running a diskchk from within the Recovery Console regained contact with the hard drive. A system restore from Safe Mode had the PC up and running again.
The Seagate HDD passed a complete test with the Seatools utility (apart from file system errors, but these always seem to be reported on XP, or maybe NTFS, PCs) . However, due to it's troublesome history, I had a look at it's SMART attribute values and am concerned. I would like some help interpreting the results:
Raw read error rate: Type = Prefailure, Threshold = 25, Value = 62, Worst = 59, Raw = 94320242, Status = OK
Seek error rate: Type = Prefailure, Threshold = 30, Value = 78, Worst = 60, Raw = 68414776, Status = OK.
Also note that the PC's 5 year hardware warranty is about to expire.
What do you reckon?
