You are grasping at straws for an explanation, and got the wrong one. I always bought Maxtor, and have had over a dozen of them. I never had a Maxtor failure and they always lasted the life of the PC which was around 5 years, until they got to the 100 GB/platter level. Then, the two drives I lost were early in the production run, when failure rates are always high. That was not long before they were taken over by Seagate as I recall. But you might as well blame it on Seagate if you want to. But I still have the replacement Maxtors (250 GB and 300 GB) going strong, around 5 years later, not to mention the six-year old 80 GB Maxtor I just removed from active service to put in a standby PC.
For comparison, when I bought Seagate, WD and Quantum (one of each), I got failures in the first year. The difference was significant, though I think reliability has improved greatly in recent years for all of them, and I have no problems now. But I also now use well-cooled cases, uninterruptable power supplies and good (series) surge protectors.
