SUMMARY

If a disk in the series of backup disks is damaged, it is still possible to restore the remainder of the disks by doing the following:
    Insert the first backup disk in the sequence, disk BACKUP 001, in the source drive (assuming for this example that Drive A is the source drive and Drive C is the destination drive) and type the following:

    RESTORE A: C:\*.* /S

    The first disk will be restored, and it will prompt you for additional disks until you reach the damaged disk.
    When it is time to insert the bad disk, press CTRL+C to exit out of RESTORE.COM.
    Place the next disk in the sequence into the source drive (A: in this example) and retype the previous command again.
    RESTORE.COM will display a warning that this disk is out of sequence, and will ask if it should continue. Respond "Yes" to this prompt.
The restoration process will continue as normal, except for the data that was contained on the bad disk. You must stop the restoration process at the bad disk and reenter the command to start the restoration with the next usable disk.
