I used to think the serial number was on the hard drive, but it seems that the Tivo serial number is located elsewhere. Having said that I can now tell you about the bad time I have had with adding a second hard drive to my Tivo. Regular readers may remember that I added an 80gig drive to my Tivo a while back. As it turns out, this 80gig drive has a bad spot on it and causes the Tivo to crash any time it tries to write to it. When I started looking into taking that drive back out I hit a brick wall….
Once you have added a drive it is a heck of a hard thing to go back to a single drive… Unless you don’t care about your stored movies. A buddy of mine…who may or may not work with me, found the following site: ftp://ftp.abs.net/tivo/
The backup directory has oodles of backup images (I don’t know for how long so get them if you need them)
More news tonight if it works!
