Well for about 2 yrs I have had an 80gb HD partitioned into 3 parts and just recently I had corruption problems that left me with a slooow everything and many window programs that wouldn't start at all including Restore.Reformatted and now have 1 partition.I'm not sure if I will use PM8 again to split the drive up in 3's.My concern is leaving such a large capacity drive whole and having to wait hours for a defrag.Maybe a 3rd party defrag program might speed things up.
