Wow, AFAIK that's the longest anyone has reported a 500GB Expander to have survived! Most never make it to their two-year birthday. Sounds like a good plan. I always keep my original TiVo hard drives on the shelf in case one of my upgraded drives fails, plus I can slip it back in to get back up and running quickly while waiting for a replacement to show up, so that's my backup plan. However having it on a thumb drive or disk couldn't hurt. I was surprised I found my old TiVo HD's truncated backup on my PC's hard drive. I sold the THD a while back when I bought a Premiere XL so I guess it's safe to delete it now. BTW, I hadn't fired up my PC for a little while (all Mac household now) and was shocked (but not surprised) to see 73 critical Windows updates - mostly security related - and 11 optional updates waiting to be installed. I think our Macs have had four or so in the same time period. Well, that will give my PC something to do this afternoon.
