Tagged: chkdsk. Sectors can develop soft errors, in which case data has been written incorrectly to the magnetic medium, or hard errors, which are cases when the drive itself has an actual physical defect in the area designated as a sector. Because CHKDSK has been updated and upgraded repeatedly with each new generation of storage hardware, the program continues to work correctly to analyze and repair hard drives of any sort.
The same process that used to be executed to analyze a floppy disk holding K, can today be executed to analyze an SSD holding 15 terabytes. However, because CHKDSK talks directly to drive hardware, it requires a special level of operating system permission known as administrative privileges. A boot drive is the partition of your hard drive that the computer starts up from. Boot partitions are special in many ways, and one of those ways is that they require special handling for CHKDSK to be able to deal with them.
If your target drive is an external or non-boot internal disk, the CHKDSK process will begin as soon as we enter the command above. One warning note: if you use CHKDSK on an older hard drive, you may find that your hard drive space was significantly reduced after running the command.
Because the Shadow Copies for Shared Folders source volume cannot be locked while Shadow Copies for Shared Folders is enabled, running chkdsk against the source volume might report false errors or cause chkdsk to unexpectedly quit. You can, however, check shadow copies for errors by running chkdsk in Read-only mode without parameters to check the Shadow Copies for Shared Folders storage volume. The chkdsk command, with different parameters, is available from the Recovery Console.
On servers that are infrequently restarted, you may want to use the chkntfs or the fsutil dirty query commands to determine whether the volume's dirty bit is already set before running chkdsk.
The following table lists the exit codes that chkdsk reports after it has finished. If it encounters errors, chkdsk pauses and displays messages. Chkdsk finishes by displaying a report that lists the status of the disk. You cannot open any files on the specified drive until chkdsk finishes. Chkdsk displays a status report, and then lists the files that match the file specifications that have noncontiguous blocks.
