Insufficient disk space to fix the security descriptors data stream.

Explanation:

Chkntfs found a problem with the Security Descriptors Data Stream file ($SDS). This file contains the Access Control List (ACL) and owner information for the files on the NTFS volume. Chkntfs was unable to fix the corrupted file because there was not enough disk space to write all the information to the $SDS file.

User Action:

Delete some unneeded files from the disk and try again. If you continue to get this message, you may have to backup the hard disk, perform a low level format and restore the information.
