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
