Detection of Write-Protected Media
Data Protector can detect and handle media that has been mechanically
protected by setting the write protection switch on.
NOTE It is recommended not to use write-protected media with Data Protector.
The following operations can detect and handle write-protected media:
• Read-only operations, such as: list, scan, and verify.
Read-only operations detect the write-protected media and proceed
without any warnings.
• Write operations, such as: initialize, erase, and backup.
Write operations detect the write-protected media and either abort
the session or skip the write-protected media. Backup sessions treat
write-protected media as unusable media and behave according to the
media allocation policy. If the allocation policy is strict, a mount
request is issued. If the allocation policy is loose, the medium is
skipped.
The detection of a write-protected medium and all changes to the
write-protection state of the medium are logged to the media.log file.
