Hey guys... I need some advice from the experts, please. A couple years ago, I bought an HR10-250 HDTivo (with the original 250GB drive). I used the LBA48 CD to add another 250GB drive. Two years of joy. Now I'm getting symptoms of HD failure ... random reboots, I can hear one of the HDs make a soft "click" noise occasionally. Shows are recording a minute late into a program, etc. I purchased two 2 500GB PATA drives as replacements and need advice on how to proceed. I would love to copy my [2x250] -> [2x500] and then use the additional space, but is this possible since I've already added a drive once? Or do I need to make a backup of just the HR10-250 file system (without recordings) to move over to the new drives? I had made a backup of the original file system two years ago, but I cannot find the tivo.bak image anywhere. I have an old computer with a SCSI cd rom and 4 EIDE ports, so in theory I could make a backup of the original drives and save my recordings .... Any advice on how to proceed is greatly appreciated. I am getting a lot of aggro from the wife regarding Lost (rebooting in the middle, lost half the episode), and usabillity etc.
