This tool reads the internal memory of LTO/Ultrium cartridges from a tape drive 🖭
More precisely, this tool can:
- Read, decode and display factory and usage information stored in the Cartridge Memory (
CM) aka Medium Auxiliary Memory (MAM) - View and modify the custom
User Medium Text Labelof a cartridge - Display basic information about the tape drive device
You need to have a go build environment properly set up, then just type:
make
And try the tool by typing:
./lto-info
By default, the tool will look for a tape device in /dev/nst0, or what is pointed to by the TAPE environment variable. To specify another device, use the -d option.
