verify MS-DOS Command

Type: Internal (2.0 and later)

Syntax:

VERIFY

VERIFY on|off

Purpose: Verifies that data written to disk was correctly recorded.

Discussion

The VERIFY command has the same purpose as the /V parameter in the COPY command; once set, you do not have to use the /V option while copying. After VERIFY has been set to ON, DOS checks for bad sectors following all data writes to disk. This can cause a slowing of such operations. An error message is displayed only if DOS was unable to successfully write your data to disk. If you enter the command with no options , DOS will display the current VERIFY setting.

Example

To tell DOS to verify all writes to disk, enter verify on DOS will check to be sure that each write to disk was carried out successfully. This condition remains in effect until you enter verify off
