Hi Everyone! I have a 1TB Bolt DVR running Experience 3 that works perfectly but is beginning to run low on storage space so I want to expand it. I am not interested in opening up my DVR and replacing the drive after cloning it, I am perfectly happy to just connect an appropriate external drive to the DVR's eSata port. After doing a couple of quick searches on Google, I found that what I am looking for is a "western digital my book av dvr expander". I noticed that there seem to be a number of models when I search Amazon or eBay but since I couldn't find a model number, I couldn't be sure which one I should get. Is Western Digital my only option? From experience I've developed a preference for Seagate over WD. Can anyone recommend a specific model that is known to be compatible with my TiVo DVR, or does anyone know what TiVo recommends? Thanks!
