Copy Videos to Computer

I have a Bolt 1 TB I would like to do three Things and have NO earthly Idea on How to do it.

1. I would like to change the HDD size from 1 tb to 2+tb without using the Esata Slot on the device. I know that i can expand the memory by doing this but i found out that if i do that and move that HDD and power up the Device without the TiVo i will lose all my recordings. The Tech told me it saves Snippets of the videos on the HDD. i would like to whole video to be on it to make it easier to move...
