The hard drive of my ThinkPad T42 finally failed after seven and a half years. I can't say I'm surprised, given that it had over 20,000 hours of use. However, I'd like to know whether it was a logical or physical failure so that I can better decide what to do with the drive.
Some relevant information:
- The hard drive is a 80 GB model from Hitachi.
- It failed after a full defragmentation. I have heard that the physical stress of a defrag operation can be the straw that breaks the camel's back.
- The first sign of trouble was that booting up took an abnormally long time. Afterwards, Windows XP somehow deactivated itself. Subsequent boots took an increasingly longer time until the computer could no longer boot.
- No corrupted files when copying to another drive.
- Scandisk complains of numerous bad sectors.
- There is no audible clicking, whirring or scraping.
- The Reallocation Event Count jumped to 91 within a short time. It had previously remained at 1 for several years.
Anyone have an idea what type of failure it was?
