LTO-CM-Analyzer

LTO (Linear Tape-Open) tape Cartridge Memory (CM) Analyzer

Description

Linux bash script which converts LTO-CM binary data to human-readable cartridge information. To dump memory data from LTO-CM tag (also called MAM (Media Auxiliary Memory)), use RFID reader. Currently, RFID readers such as ACR122U, SCL3711 and Proxmark3 are able to dump data from the tag and save it to file. You can also use tape drive to do this. Check the following repos and websites for more information:

Motivation

There are several LTO CM reader/analyzer in the market, however, these are proprietary solutions and they support Windows only.
