Out of all the HD's I've ever had going back to my 286 I've had more Maxtor than any other brand. I've only had two drives fail and only one of those was a Maxtor. The Maxtor was about 5 years old and the other drive was a WD that was only 6 months old.
Main System:
Maxtor 5T040H4 [Hard drive] (40.98 G

-- drive 1,
rev TAH71DP0,
SMART Status: Healthy
Maxtor 6Y160P0 [Hard drive] (163.93 G

-- drive 0,
rev YAR41BW0,
SMART Status: Healthy
In my old system I have setup in my boys room as an internet backup machine I have another Maxtor running in it 10GB

Can you guess how old that drive is?
I would like to know DoG if you have your HD's to shutdown under your power settings. If so, what is your setting. I have always set my drives to stay on all the time and never shutoff. I think kicking on and off is hard on them much like our motherboards.
Just my $.02
