I had this problem for awhile now, but I thought I had fixed it. Anyway I'm using a Maxtor diamondmax 10 80gig hardrive
( ) and it had been running good for two years. But a month ago it started becoming ridiculously slow, windows would take literally 10 mins to boot up. I tried a system restore and it failed. Did a disk check and showed nothing but it took freaking two days to complete!. Then I reformatted the disk and reinstalled and windows and everything seems good again for two weeks. But starting from yesterday I noticed it started crapping out again and becoming super slow. I ran HDTune and it told me my harddrive transfer rate is only 1.8mb/s read and 1.8mb/s write .... Whereas before it was in the 60's... I noticed this happened after I downloaded about 5 gigs worth of files off bittotrent over night. Is this problem specific with maxtor and is there a document fix? I really don't want to reformat everything again...
