LTO-5 Half-Height SAS Tape Drives
WORM data cartridges

CAUTION:
Write-protection will not protect your cartridges against magnets. Write-
protection will not prevent a cartridge being erased by bulk-erasure or
degaussing. Do not bulk erase LTO format cartridges. This will destroy
pre-recorded servo information and make the cartridge unusable.
5.4 WORM data cartridges
The LTO–5 tape drive includes support for both re-writable and Write-Once,
Read-Many, WORM, data cartridges. WORM cartridges provide an enhanced
level of data security against accidental or malicious alteration of data on the
tape cartridge. The WORM data cartridge can be appended to maximize the full
capacity of the tape cartridge, but the user will be unable to erase or overwrite
data on the cartridge. Any attempt to modify a WORM cartridge to enable
writing over existing data will result in the media becoming permanently write
protected. It should still be readable in a WORM drive, depending upon the
severity of the tampering, but no further appended backups will be possible.
WORM data cartridges are clearly identified by their distinctive, two-tone
cartridge color. They can only be used with LTO tape drives that support the
WORM feature.
To check whether your backup or archive software application supports WORM
cartridges, refer to the software manual.
5.5 LTO-5 tape drives and encryption
The LTO–5 tape drive includes hardware capable of performing data encryption
at full speed while writing data, and decrypting when reading.
Encryption is the process of changing data into a form that cannot be read until
it is deciphered, protecting the data from unauthorized access and use. LTO–5
tape drives use the strongest version of the industry-standard AES encrypting
algorithm to protect your data.
To make use of this feature you need:
● A backup application that supports hardware encryption
● LTO Ultrium 5 media (recommended) or LTO Ultrium 4 media; no encryption
will be performed when writing earlier generations of tape
