In the old days, I used Partition Magic which can support up to 80GB hard drives.
But now it seems needing to buy a copy that will support 1TB drive or 2TB drive and pay $60 or $70 for it… (the newest version on Amazon.com is a 2003/2004 version)
Is the free GParted very reliable?
It seems that the Vista or Win 7 Disk Management Tool can shrink a partition but if there is data already on a 200GB partition but the data is everything in a 160GB region, even though the data is only 70GB, then the tool can only shrink down 40GB to create a new partition. It cannot shrink down 100GB and create 4 more 25GB partitions.
