Before Maxtor was bought by Seagate, I remember some people saying that Maxtor had extreme reliability problems. It was pretty obvious due to their fat contract with Dell and other major suppliers.
I wish I knew this before I got this Maxtor HD.
Actually what happened was that Dell used a ton of them and because Dell had a forum, and there were large number of users at that forum and on usenet, every Tom, Dick, and Harry that had a failure all assembled in one place to proclaim "me too".
So if you have a normal 5% failure rate and 40,000 customers, and forums where 2,000 of those people gather, do the math- 5% of 2,000 is 100.
If you saw a thread here where 100 different people said their brand X product failed, it'd look like crap even if the actual failure rate was no worse than any other (drive) subject to the same environment.
On the other hand, most of Dell's low end cases didn't do so well cooling more than one HDD, as only the first one was butted up against the chassis air intake holes (being vertically oriented and parallel to the front of the case).
