If i was you i would go for a Samsung or Seagate drive...
For the simple reason that most hard drive manufacturers reduced the terms of there warranty from three or five year warranties down to just one, Clearly as a cost cutting measure...
Although as you can see in my signature i own two Maxtors which i have not had any problem with, probably down to my harddock cooling rack doing a good job....
From very recently I now restrict my hard drive purchases to those manufacturers prepared to stand by the reliability of there drives..
Both Samsung and Seagate still offer an extended warranty on there drives of three and five years respectively...
Keeping a hard drive cool is the key to running a drive to its maximum potential for reliability...Hard drives are also happiest when spinning at a constant rate, so try not to turn your pc on and off too many times a day unnecessarily...
If your Overclocking make sure that the Pci bus is fixed at a standard multiple of the Fsb, as running the IDE bus out of specification can cause damage to your drives and corrupted data...
Hope thats helped you to make a decision...
