Advertisements Ok, I got the TivoHD today. It's all set up. I have a 400 gig and the Tivo drive in SATA USB boxes. I'm on an Intel Mac and am able to boot from the Linux Boot CD from MFSLive. I'm a little confused on the correct Unix commands. I don't want to overwrite my internal drive. I have read the directions and am still confused. Any help would be much appreciated!
