I have a Series 3 HD and a Premiere both with lifetime that I upgraded the original drive many years ago. Both have been in use for years and I am growing concerned that the HDs will eventually fail. I have the original HD for each unit packed away. My question is if those drives, since they have no sw update for years, are even useful any longer in the event of a failure? I have seen the discussions about the Series 3 HD potentially having a problem getting the update for the current guide service. I have also seen various comments about HD images. Are there images that can be obtained that will restore these units in the event of a HD failure? Finally, is it possible with MFS Tools or some other package to clone my existing drives that have been expanded, or better yet, make my own image that could be stored on my server? Please excuse my ignorance but I have not tinkered with MFS tools since the day I installed the drive in the Premiere, which was also that day I bought it New, so quite some time ago. Thank you to all those who continue to keep these forums alive.
