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
