Resurrecting a 25-Year-Old Tape Driver with AI

The author enjoys recovering data from old QIC-80 tapes, a popular backup medium in the 1990s. These tapes require the outdated ftape driver, only compatible with very old Linux versions (CentOS 3.5). Using Claude Code, an AI model, the author modernized the ftape driver to compile and run on modern Linux kernels. Through iterations and minor manual adjustments, a loadable kernel module was created, successfully reading test tapes on Xubuntu 24.04. The author shares lessons learned collaborating with AI, emphasizing clear instructions, understanding AI limitations, and leveraging AI as a skill multiplier.
