Parition Magic is a worthless waste of harddrive space, its pure and utter TRASH. It has killed more paritions of mine than I can count.
I do simple actions on my paritions, and many times they result in corrupted paritions, I have done this on many PCs, many different Parition Magic versions (including the latest) with many different harddrives and OS versions. The results have always been the same, corrupted paritions. It will start to perform its action, error, and then the partition will die.
I actually just had this happen, AGAIN YESTERDAY!, it killed 2 paritions on my sisters boyfriends harddrive when doing this very thing! We were going to manually parition for mandrake, ended up having to compeltely remove and format the offending partitions.
Do not use Partition Magic!!!!!!!! It is very very bad!
