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.
