How to Cancel ScanDisk
- 1). Press "F5" when your computer screen reads "Starting MS-DOS" during boot up. You will only have a few seconds to do this, after which MS-DOS opens and ScanDisk automatically starts.
- 2). Press and hold the "Ctrl" and "C" keys if the scan is already in process.
- 3). Repeat Step 2 until the scan cancels. Depending on what phase of disk checking is occurring, the Ctrl C command will not always cancel ScanDisk. ScanDisk is not cancelable during certain phases of disk checking, so whenever possible it is best to stop the MS-DOS prompt using the F5 key before it even starts.
