Info: Selects whether DOS should verify (check the CRC▲ on) each sector
after it is written to disk.
This slows down disk write operations, but it ensures maximum
data integrity.
DOS Fn 54H returns the current DOS verify status.
Notes: ■ The Verify flag is a system-global setting. If you change it,
you should restore the original value before exiting.
