Maxtor's aren't that bad at all, as people have said, they sell an awful lot of drives, more than any of the other hd companies and thus they have a lot of failing drives, it's still a tiny percentage of the total though. I think it's fair to say Maxtor have had some problems with particular models of drive failing more than would be typically expected, various models of the Dimamondmax 9 range spring to mind.
I've got 3 x 300Gb Maxline III's here, and they are all fine so far, the oldest has put in a good few years service.
Incidentally I've still got a 20Gb IBM Deathstar that works fine, although it isn't used anymore. I've also got a 6.4Gb Maxtor built sometime around the end of the last millennium, which works fine, although it does make that old school Maxtor clatter when seeking, they all did though
Only drive I've ever actually had 'fail' on me was a Samsung Spinpoint 160Gb, bear in mind I had 2, 1 was over a year older than the other and the older one still works fine, it serves me day in and day out in my secondary machine, no problems there but one, the newer one which wasn't much more than 14 months old failed on me ...just one of those things really.
