Lost one of those two new 1TB drives a couple weeks ago, WTF. 10 months old and rarely accessed (was a manual backup drive).
This happened 3 days after I lost the drive in my laptop.... serious WTF.
So I bought a 320GB drive for the laptop, and threw in 4GB of RAM. Installed everything and had blue screens of death about every 15 mins. I searched a bit for the error, found people talking about hard drive issues (ITS NEW!).. Found one post about the internal battery and it may be going bad, so I took it out and left it out. Been fine ever since, haha.
Now I need to buy more drives for the tower. Oh the frustration..
