WORM Data Cartridges

32 LTO-5 Tape Drive User’s Guide

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 Ultrium tape drives that

support the WORM feature.

LTO-5 Tape Drives and Partitioning

The LTO-5 tape drive supports two tape partitions, when used with

Ultrium 3TB R/W cartridges. Tape partitioning is not supported with

WORM cartridges or with earlier generations of cartridge. See your

backup application's documentation for more information about

partitioning media.

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
