I got the same error message trying to resize a partition , not on C: drive fortunately. The partition (D:) disappeared, even when I explored 'my computer'. I tried CHKDSK, but WinXP would not open the drive. I solved the problem the following way... Opened PartitionMagic, Operations, Advanced, Change Drive Letters... I put a "D" in the text box and my partition reappeared!!! All the data is there, and it's accessable. If you made the PartitionMagic "rescue disk" -- which looks like a dos-style PM --, you may be able to solve the issue that way. Best Luck, Fossil's Friend
