Compatibility
HP Gen 3 Ultrium drives are specified to interchange data cartridges with other tape drives 
that comply to the LTO U-18, U-28, and U-316 specification documents:
This specification is only applicable when:
Cartridges carry the Ultrium logo.
Cartridges are not damaged or faulty.
Cartridges are read on a drive in good operating condition, and have been written on a 
logo-certified drive that is in good condition.
The environmental conditions (including DC voltage supplies) are within the specified limits.
NOTE:
HP Gen 3 Ultrium drives do not support 10 GB and 30 GB cartridges. HP 
recommends the use of the 
SET CAPACITY
 SCSI command to shorten standard cartridges 
logically for test purposes.
Future compatibility
In future, HP Ultrium drives will always be capable of reading and writing tapes from the 
current generation and one generation before, and reading tapes from two generations before. 
HP Ultrium drives will always maintain write and read compatibility with other manufacturers’ 
Ultrium drives and tapes that meet the LTO Ultrium format specification.
