Remarks
- A volume's dirty bit indicates that the file system may be in
an inconsistent state. The dirty bit can be set because:
- The volume is online and it has outstanding changes.
- Changes were made to the volume and the computer was shut down
before the changes were committed to the disk.
- Corruption was detected on the volume.
- The volume is online and it has outstanding changes.
- If the dirty bit is set when the computer restarts,
chkdsk runs to verify the file system integrity and to
attempt to fix any issues with the volume.
