I was using Partition Magic to resize a partition when it stopped an gave the error message, "Information mismatch in directory entry." Now the drive letter has disappeared, and I can't access it! The help file for Partition Magic says that NT will rebuild the root directory the next time the OS is started, but that didn't happen. It looks like the data is still there, but Windows can't see the partition, so I can't run CHKDSK. I'm using XP pro with SP2.
