currently, i have no problems with that :)

all my failed drives were maxtor. all of them were late models (bought
in last 3 years). probably all due to overheating. seems you really need
to be careful. most of them were replaced in warrantee though.

i got one 2 under control now, in an open case with lots of space
inbetween them. they stay around this temperature. closing the case 
makes them very hot indeed. so i suppose fans are really necessary indeed.

where did you get this info?

you know one for linux?
