Our Tivo HD unit died recently. There's nothing that puts the kids faster into a whining mode than telling them they can watch TV but not have one of their shows available. Here I purchased a 2 terabyte upgrade off of Ebay. There are a few aftermarket sites that sell hard drive upgrades such as Weeknees.com. There price was $400 for a 2 Terabyte HD. Instead I looked at Ebay and found several "reputable" sellers that were selling them from anywhere between $111 to $150 for a 2 Terabyte HD. I bought mine from this seller.

Replacing the HD is quite easy. You need a torx screw driver but after removing the cover and then another 8 screws, you put in your new HD and then reverse the process. The HD came with instructions on how to do the install.

Here you can see the old 160 GB HD and the new HD. Our HiDef recording capacity went from 20 hrs to 320 hrs.
