Write-Protecting A Tape Cartridge - Digital Equipment MicroVAX 3600 Operation

NOTE: Do not write on the tape cartridge or attach labels to the top, bottom,
or sides of the cartridge.
3.1.2.3 Write-Protecting a Tape Cartridge
Write-protecting a tape cartridge prevents accidental erasure of information
stored on the tape. You can write-protect a tape cartridge in two ways:
• Set the write-protect switch on the cartridge to the write-protect position.
• Write-protect the cartridge by using operating system commands described
in your system software manuals.
Your system can read information on the tape regardless of the position of
the write-protect switch or whether writing is software disabled. However,
the system cannot write data to the tape when the write-protect switch is set
to the write-protect position, or when writing is software disabled.
When you use a cartridge to install software, make sure the cartridge is
write-protected. Two icons on the switch indicate the write-protect status, as
shown in Figure 3-7. An orange rectangle is visible when the switch is in
the write-protect position. If you do not see an orange rectangle, slide the
switch toward the label slot.
