Write-protecting an UDO disk
Each 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 ).
