No problem with Maxtors here. I've had 2 of them for almost 4yrs and they're still working fine till this day.
I've heard horrid stories about WD and even MORE horrid for Hitachi.
Seagate drives are loud. I haven't heard any other complaints besides that.
Samsung drives run hot like fire(compared to other HDD's), but they're very quiet.
In general, any HDD without FDB technology(which most earlier Seagates lack) is loud.
If chosing a new harddrive, I'd pick from my experience which is Maxtor.
While I don't question their reliability, I seriously doubt that statement.
I've always taught it was WD, Maxtor, and then Seagate. Yes, in that order.
