When was the last time you've done a format? Even if it's been a while it'd take a lot of junk to slow it down to that point... my grandmas 10gb that came out of a 6 year old PeoplePC machine doesn't read that slow =/
How about checking to see if the drive is severely fragmented?
A lots already been covered and I'm strapped for ideas on what would cause it to do that.
Yeah but ideas are running low...key word is SHOULD not lol, but in my experience with computers they generally do a lot of things they shouldn't. But at this point I'm stumped =/
