Certify Media can used in the following ways:
vCertify Diskette
This selection enables you to verify the data written on a diskette. When you select this service aid, a menu asks you to select the type of diskette being verified. The program then reads all of the ID and data fields on the diskette one time and displays the total number of bad sectors found.
vCertify
This selection reads all of the ID and data fields. It checks for bad data and counts all errors encountered. If an unrecovered error occurs, or recovered errors exceed the threshold value, the data on the media should be transferred to other media and the original media should be discarded.
The Certify service aid will display the following information:
±Capacity in bytes
±Number of Data Errors Not Recovered
±Number of Equipment Check Errors
±Number of Recovered Errors
If the drive is reset during a certify operation, the operation is restarted.
If the drive is reset again, the certify operation is terminated, and the user is asked to run diagnostics on the drive.
This task can be run directly from the AIX command line. See the following command syntax: diag
