Use the Medium Verify operation to verify that:

• A disk is readable.
• A disk has no errors on it.
• The format of a disk's contents is correct.

This operation can take several hours, depending on how much data is on the disk. If there are errors on the disk, it will take longer.

If errors are found:

• You may want to cancel the Medium Verify operation if you have other tasks that use the drive.
• You can copy the data to another disk using the Medium Logical Copy option.
