maybe i have missed something i don't understand why one would want a hard drive the size (nowadays) of 40,60 gig that would take hours to run a thorough scan and defrag instead of buying amotherboard capable of running say 4 drives of 15 to 20 gigs like abit kt7a raid one with programs,one for napster one for photo and video and one to play with linux to expermient with. i personaly don't get it .I would like everyone like to have a 100g drive but you will be waiting all day to use your comouter to do these tasks even if you run them at night.the initial cost of the board is cheap compared to large drives.maxtor isselling 15g drives now for $39 after rebate I know i'm opening a can of worms now.you could scan each drive at your leisure
