Ugh, the Seagate drive is louder than the original Fujitsu. I can hear it seeking, oh well. Went from 160GB to 500GB, gives me a bit more room to work with now.
I can't stress enough to everyone, BACKUP your stuff. If you can't do a live backup type thing, atleast do it once a month. I would be in a massive panic if I lost the stuff that was on that drive.
