Directs MS-DOS to verify that your files are written correctly to a disk and
displays the status of verification. For example, you can use this command
to make sure data is not written to a bad sector. You can use this command
either at the command prompt or in your AUTOEXEC.BAT file.
Specifies whether MS-DOS should verify (ON) or not verify (OFF) that
write operations are done correctly.
For information about checking a disk for bad sectors, see the <CHKDSK>
For information about verifying files as you copy them, see the /V switch in
the <COPY> or <XCOPY> command.
