I was swapping around some drive letters using the disk management program in XP and fumble fingered my way to setting one of my 300GB movie drives to active. Is there a way for me to reset the drive back to a non-active state without having to copy all of the data to another drive and then delete the partition on this drive? Of course, I don't want to lose the data. As I remember the earlier versions of partition magic (before NTFS) let you do this but the newer versions do not.

Thanks!
