10 Erasing a Pre-Written LTO Tape
Caution: Do not bulk erase Ultrium format cartridges. This destroys pre-recorded servo information and
renders the cartridge unusable.
The erase feature in the backup software is the preferred method for erasing an LTO tape. To prevent
erasing a tape, slide the write-protect switch to the right.
Note: Write-protection does not prevent a cartridge from being erased by bulk-erasure or degaussing.
