Running SCANDISK /UNDO results in the following error message:
This error occurs when the SCANUNDO.DAT file on the Undo disk has a read-
only attribute, which ScanDisk attempts to clear before opening the file.
Because the disk is write-protected, attempting to change the attribute
fails and results in the above error.
Since ScanDisk needs to change the read-only attribute on the Undo disk,
first verify that the disk is not write protected. If it is write-
protected, remove the write-protect tab or slide the write-protect tab to
the closed position, then try running SCANDISK /UNDO again. If the disk is
not write-protected, the disk may be damaged. Run SCANDISK on the Undo disk
to try to correct any problems on the floppy disk.
