[<<Previous Entry] [^^Up^^] [Next Entry>>] [Menu] [About The Guide]
Function 2Eh (46) Set or Reset VERIFY Switch
Turns the disk verify operation on or off.
On entry: AH 2Eh
AL 00h to turn VERIFY off
01h to turn VERIFY on
DL 00h
Returns: Nothing
--------------------------------------------------------------------------
Function 2Eh turns the DOS VERIFY switch on or off. If VERIFY is on,
DOS reads the CRC (cyclic redundancy check) bytes of the just-written
data, and verifies that they are correct. Note that setting the VERIFY
switch ON does NOT cause a read-after-write verification of data
copied to the disk, only a verification of the CRC bytes.
Notes: In DOS 1 and 2 only, DL must be set to 0 before this
function is called.
Network disks do not support the verification
function.
Use Function 54h (Get Verify Setting) to determine
the current state of the VERIFY switch.
