I would guess that the failure curve of a hard drive is much like
that for a lot of electronic equipment. It is probably a sort of
wonky "U" shape.
If it fails then the drive is likely to fail quite early on in its
life. After it passes this period then it is more likely to fail
after some years as it gets older.
Does anybody know approximately how long this period is of relatively
high risk of early failure? This must vary from one model of hard
drive to another but, very approximately, after what period of time
would it be?
I may be wrong but I would guess there is a bit of a "knee" in the
shape of the reliability curve where the risk of failure changes.
If I get a new ATA/IDE hard drive I don't like to use it for live
data until it has been running on test for a while. But how long is
sensible for this test period?
At a usage pattern of 10 hours a day for the hard drive, would this
period be three or four days? A week? Three weeks?
