I have a HD removed from my Tivo during an upgrade and repair. The specs look very similar to the internal HD on my iMac: 40.0GB AT Quantam Fireball.lct (Part# QML40000LD-A) I would like to make an external firewire drive out of it. I have seen enclosures on the internet from about $40 to $100. Here are my questions: 1. I am not experienced in dealing with Hardware issues other than installing RAM or an Airport Card. Is this easy to do? 2. Any suggestions on a good low price enclosure to buy and where? 3. This drive crashed on my Tivo, but the guy that fixed it said it could be reformatted and used. Is this the case? 4. If connected via firewire will it be just as fast as the internal drive on my iMac DV 400? Will I be able to edit iMovies and listen to mp3s stored on this drive? Thanks for the help.
