My old 3.5gb Maxtor from 1998 is still working.
All my older maxtor drives still work, but the last 3 years we've (at work) got a few dozen "newer" (Well 80 at least) ones die within a year, or a bit later. Far more then WD drives that seem to be going steady.
Does have to work with heat perhaps, Maxtor drives are less heat tolerant then other makes.
