Hi Nando,
I know you did not ask, but like to be helpful:
I have had 20 computers running at the same time with fewer failures.
What are you doing to the HD?
Turning it on/off frequently will do it. I set one computer to turn off after 2 minutes, HD failed within 7 months. Checking the on/off cycles, exceeded design limits of HD.
Secondly, Hot HD cooling helps.
Good luck on your next.
Should I say anything about backups? I copy important data to another computer for backup.
If you have one, then a second disk works, considering how cheap they are, saves bunch of work later.
Lately started using external USB drives for backup, $70 for 120Gb, $130 for 500Gb.
Have fun, (Fake it for now)
Scott.
