HP LTO Ultrium 4 drives are specified to interchange with un-encrypted data cartridges from other tape drives that comply to the LTO U-28, U-316 and U-416 specifications:

Future compatibility:

In the future, HP LTO Ultrium drives will be capable of:

Reading and writing tapes from the current generation

Reading and writing tapes from one earlier generation

Reading tapes from two earlier generations

HP LTO Ultrium drives will always maintain write and read compatibility with other manufacturers’ LTO Ultrium drives and tapes that meet the LTO Ultrium format specification.

Note – Currently, only LTO4 media is encryption-capable on the LTO4 tape drives.

While LTO4 can read and “write” to LTO3 media, if an LTO4 drive encrypted data on LTO3 media, then LTO3 drives could not read those tapes. Therefore, when LTO3 media is inserted into an LTO4 drive, the encryption capability is disabled and the drive will write non-encrypted data without notification.
