How Do I Change Modes When Using CHKDSK?
- 1). Right-click the drive you wish to scan on your computer and select "Properties" from the context menu that appears.
- 2). Click the "Tools" tab from the top of the dialog box that appears.
- 3). Click the "Check Now" button under the "Error checking" heading. This will launch the CHKDSK utility.
- 4). Locate the second radio button on the CHKDSK dialog box titled "Scan for and attempt recovery of bad sectors." This option changes CHKDSK from its default mode of scanning for only logical errors to its alternative mode of scanning for physical failure points on the drive platters.
- 5). Select this second radio button to enable the physical scanning mode. This alternative mode of disk checking requires several hours, three to five in most cases, to complete a full scan, especially on hard drives over one terabyte in capacity.
- 6). Click the "Start" button to begin the scan.
