It is important to keep the firmware of your LTO drive up-to-date as changes are made to keep it working as trouble-free as possible. Use SymplyATOM or IBM's ITDT to check your SymplyLTO drives current firmware.
If you are using macOS you can use [SymplyATOM] to upload the new firmware, if you are using Windows you can use [IBM's ITDT] application, both applications are available to download from this support portal.
Pay careful attention to which firmware you download and install, ONLY install the LTO firmware for drive you have.
