Hello Mac-wise,

A short de-lurk here from a longtime user with limited hardware knowledge:
A friend asked me for help with her first generation white MacBook (2GHz Intel). Short history:
- original HD dies one month out of warranty. Replaced by local repair folks.
- second HD dies 6 months later, replaced at no charge.
- (maybe not relevant) keyboard functions badly or not at all: replaced at owner cost.
-third hard disk dies, the Hitachi 120GB the repair folks put in there as replacement just over a year before.
- owner asks me to look (does not want to see repair folks again). Mac is mainly used for Mail and web, mostly at home.

I replaced the HD with a known good one (clone of my own) - all worked fine.
Then put a fresh 120GB in, installed OS X and ran Apple Hardware Test. All is fine.
But...
No one trusts this MacBook anymore: will the 4th HD fail too?
Could there be a power supply malfunction or something else that goes unnoticed, but kills the disks one by one?
In no way has this MacBook seen real heavy duty service or treatment. (My own of the same vintage has been used constantly and intensively and never shows any problem).
I'm happy with any opinions, and with the new forum in general!
