Advertisements My sister has been on me ever since she saw bpunc's post with his external hard drive enclosure. ( e r e b o s . n e t » Blog Archive » TiVo Bolt Hard Disk Upgrade and Take Apart ) Well I finally got around to doing it and she was very pleased to say the least, I did order the cable that bpunc suggested and took it one step further and went and mounted the esata end of the cable into the rear of the Tivo. It took me about three hours of fiddling around with the dremal tool and a xacto knife and it was done, I also ordered up the DVRdaddy enclosure and the WD 3TB Green AV-rated (EURX) on the advice of ggieseke and some others. The end result is a Bolt with 478 hr's of HD recording space, needless to say my sister is now a happy camper Just thought I would share my experience, and to anyone thinking of trying this mod take some advice, just take your time.

So do yourself a favor and stay away from the headache of the DVRdaddy.

First thing that must be done is to remove the two screws marked yellow, next is to loosen the two screws marked red as they don't come completely out of the mechanism. This shows the yellow screws removed and the red screws loosened. Next you want to use the two red screws to assist you in removing the mechanism by pulling straight up on them away from the main board. ( be gentle with a slight rocking motion from left to right but make sure the screws are completely lose before trying to pull them away from the main board ) This picture shows the cable card mechanism coming away from the mainboard mating surface. After removal it should look like this. Hope this helps.
