hey, no there isnt to my knowledge at least. you have to re-format. however, you can send ur files to another computer temporarily to avoid losing anything.
Yup, my brother went ripe Partiioning to Raiding and you have to Forma the bad johnny, but my bro has 2 X 200gb harddrives and i only have an 80 so he lost alot.
Umm, partition Magic could do...but it's also named partition tragic becuase it can fail (in which haveing you to reformat), reformat itself and do such crap you wouldn't imagine.
My best bet is burning CDs with your files. They will be useful backups for later also
