It was really interesting reading these post to find out that Seagate bought Maxtor (I think maybe you got mixed up - no biggie). It just so happens that I've had MANY problems with both of these drives throughout the years. I found a Seagate not long ago for a very good price and decided to buy it despite something in the back of my head telling me to go for the more expensive WD beside it. Of course, once I get it home it failed almost immediately. That pretty much sealed the deal for me - I'm with WD from here on out.
I understand that they're both supposedly good manufacturers, but I can't help but recognize that all of my WD drives have been stable, long lasting, and generally smooth sailing all the way. Unfortunately, this has been far from the case with Seagate/Maxtor.
