Interesting. I have another WD (30GB) disk which clearly does suffer
from overheating during vigorous activity. In fact I can hear a
'klunk' from a mechanical relay which seems to be a thermal cutout
and the disk is useless until I power it down for 20 minutes or so
to let it cool off. Needless to say I don't depend on it!
I also have two newer WD 80 GB drives which work fine, so I'm hoping
that WD has improved their drives in the last few years. The prices
have dropped so low I'm amazed that the drives work at all.
Which brand do you prefer?
