Interesting. Especially since on many machines I have had 0 errors when running performance tests to fill up the disks, but days/weeks later when the machine was idle all of a sudden a drive or two would drop. Not only that, but all of the drives that I've looked at have failed the powermax simple test.
I think this argument may be a bit convenient for Maxtor. If this is related to the lack of TLER, then I think the drives are all decaying like crazy, and only when put in RAID controllers is it noticeable. Home users would have no idea that they have decaying drives unless they decided to do something like run powermax.
Who knows, really... probably best to avoide these AND the Maxline IMHO (as well as the WD SE).
