I bought 2 of these drives from SCAN 06/02/10 and they are both making a loud clicking noise and won't boot up and not showing in the BIOS. I had them in a Dell Studio XPS 435MT that I sold a few months ago and they both seemed to be fine. I put them into a Dell XPS 8300 and thats when the problem began. I was getting an inaccessible boot device error message but now nothing. I sure these had a 3 year warranty when I bought them so any ideas before I rma PLEASE!
