Emo, like i said its different for people..defragmenting helps my win file system stay alive and i notice it through the "sounds" my harddrive makes when it accesses lots of files...

anyway, that same HD of mine crashed february earlier this year and i lost my work since i got it. still dont know the reason why it did. all i know is that windows froze up when i was booting it. and when i booted back, everything was corrupted, partitions were gone
