Ok so im experiencing high disk with windows 7 64 bit whereas I didnt seem to have this with 32 bit. Usually with processes such as System or svchost. This is with 2 HDs whose SMART status comes up as good but it is still possible they are at fault cause one is old and the others age is unknown. In both instances the disk usage occurs on clean installs. I was wondering if this could be a problem specific to windows 7 64 bit?
