Error Message:

Adjusting instance tags to prevent rollover on file filename.

Explanation:

Chkdsk is adjusting an internal file system structure for greater reliability. Each attribute record in an NTFS file record segment (FRS) has a unique tag ID. If the counter used to assign tag IDs for a particular FRS rolls over, duplicate tags would be created for different attribute records. This would mean that a routine that fetches attribute records could get the wrong record which could result in a loss of data.

User Action:

No action is needed.
