I have an upgraded DTiVo with a 160GB drive plus the original 40GB drive as drive b. The 40GB drive has developed bad sectors and the TiVo will no longer boot. As a first quick fix using what I had on hand, I did an image copy of the 40GB drive onto an 80 GB drive (filling only half of the drive of course) but the 160+80 TiVo wouldn't boot (just got the Welcome screen). I wasn't surprized. First of all, when I did the copy there were about half a dozen read errors so clearly the data on the 80GB drive is suspect. On top of that, I really should have copied the 40GB drive to another 40 GB drive--I just didn't have one on hand. Is it worthwhile to buy a new 40GB drive and give this a try, or will the bad data be my ultimate downfall? So my second option is to issue a mfs command to remove the second drive from the 160+40 configuration leaving just the 160GB. Can this be done and if so what is the command that I need to use? Does anyone have any other suggestions. I still have the backup of the original 40GB drive that came with the DTiVo (two years old) so if worse comes to worse, I can rebuild the system from scratch and lose my current programming. I'd like to try other recovery options first though if there is a chance I could get the system running again. If I do have to rebuild from scratch, I have a second DTiVo that is still working fine. I was thinking I might back that system up and use its image to rebuild my broken system. One way of doing this would be to do a straight disk-to-disk copy of the 160GB and 40GB drives in that system onto the 160GB and (new) 40 GB drives in the dead system. Again, does anyone have any other suggestions here?
