Verify Ü
ßßßßßßß
Tells FreeDOS whether to verify that your files are written correctly to
a disk. You can use verify to make sure data is not written to a bad
sector on a disk.
Syntax: VERIFY [on|off]
on|off Specifies whether FreeDOS is to verify that write operations
are done correctly. The on value enables this verification
process. The off value disables it.
Displaying the current status
Use the verify command without parameters to find out whether
verification is turned on or off.
Affecting performance
Turning verify on slows down all disk operations. This is because
FreeDOS makes sure that the files were written correctly to a disk.
Verifying files as you copy them
To verify that files are copied correctly, you can also use the /V
switch with the copy or xcopy command.
Example:
C:\>verify
VERIFY is on
C:\>verify off
VERIFY is off
C:\>verify
VERIFY is off
