MFS Tools is a set of utilities for those who wish to get the most out of their TiVo. The primary focus is in backing up TiVo drives, and adding extra video storage capacity. Other simple utilities not directly related to TiVo upgrades are included.
great app, works nicely
Works and fast.
The code is well written. After updating the Mac port, I successfully replaced a failing HD in my TiVo and it's been running OK for more than 3 months. To use this, you do need to be able to run command line programs and this involves formatting hard drives; so, one must use the restore function carefully and understand a little bit about how the OS names hard drives in /dev.
