Operations
Write-protecting an UDO diskEach side of an UDO disk can be write-protected.
With rewritable disks, this prevents existing files from being altered or erased, and new files from being written to the disk.
With WORM disks, existing files cannot be altered or erased regardless of whether or not the disks have been write-protected. However, write-protecting a WORM disk prevents additional files from being written to the disk.
To write-protect an UDO disk, slide the red write-protect switch to the left, as indicated by the arrow on the cartridge (see Figure 4).
