After you restore or copy a lot of data and the NTFS file system security information that is associated with that data, Chkdsk.exe may report errors on the partition. This problem may occur even if you restore or copy the data to a partition that you know to be error-free. Chkdsk may report errors that are similar to these:
Note that the number of reported errors and the security IDs may vary. The index entry IDs and the file numbers may also vary.
CHKDSK is verifying security descriptors (stage 3 of 3)...

Security descriptor verification completed.
Windows found problems with the file system.
If you then run the chkdsk /f command on the partition and you perform an audit of the applied permissions, some files and folders may have lost user-defined permissions. These permissions may have been replaced by default permissions that give access only to Local System and Administrators.
This problem may occur no matter which program you use to restore or copy the data. The problem has been reported after restoring data (with its security information) by using the Ntbackup.exe tool, and after copying data (with its security information) by using Xcopy.exe with the /o and /x switches.
The design of the NTFS file system requires that security descriptors be written in blocks, and that at least 20 bytes be left free at the end of each security descriptor block. This leaves space for a security descriptor header. However, in some cases, a miscalculation by the NTFS code might cause security descriptors to be written near the end of a block so that less than 20 bytes free space is left.
Chkdsk.exe then removes these security descriptors and replaces them with default security descriptors to make sure that a minimum of 20 bytes of free space remains at the end of the block. This causes a loss of user-defined security for some files and folders.
