On my Boss' machines, he's had two HDs become corrupted. On both, the corruption occurs exactly where/when Mail saves the index of his mail directory. He has over 1000 mail messages in his mail box.
I've taken the HDs out and reformatted them with low-level format, and tested them with Norton. No bad blocks, everything's fine. But after a while they start making scratching noises again when it starts to save the index.
Anyone know of a known bug with Mail that might cause this? One of the HDs is brand new. It could be coincidence, but I find that hard to believe.
