hmmm... i noticed a slight click noise yesterday when my comp locked up. it's easier to hear now that i have that mammoth volcano11 fan out of there. i just took out the main OS drive, formatted on another, and started over. guess the odds of getting 2 bad hdd's in a row are pretty high when it comes to WD. pc has been up for more than 9 hours..... so far....... we'll see how this fares out. perhaps i should try to rma this thing, but WD is such a pain to get an rma through. last time it took about 7 weeks before i got my drive back.
