I did a Windows CheckDisk in PMagic for both the C: and F: drives under Operations. It went through 3 stages (file, index, security descriptor, and usn journal verification) in DOS. It seems like it found errors in the C: drive --> "Correcting errors in the Volume Bitmap. Windows found problems with the file system. Run CHKDSK with the /F (fix) option to correct these. Press any key to continue..."
It would not allow me to do a CheckDisk for the extended or unallocated space.
I CANNOT create a partition at all in any unallocated space.
