I have a new 2 TB HDD in shipment right now, but it's bare, and I just realized I may not be able to copy anything off the dying/dead HDD.
Is my other Premiere the same model? Can I extract the HDD from Premiere #2, copy it to the bare HDD, and insert back into Premiere #1 for happiness and joy?
First you need to take the drive out of the Premiere, hook it to a PC (and if it's a GigaByte brand motherboard say so first so I can tell you how to avoid having it screw up the drive), and set the PC to boot from the CD/DVD deck and put in a bootable cd like the MFS Live cd v1.4 or the Ultimate Boot CD--for owners of Series 4 or 5 TiVos the MFS Live cd can't be used for making or restoring backups, but it still handy to have around. The main idea is not to boot into an Operating System that might do something to the drive without being specifically instructed to, the way it would have to be in a Linux environment.
Then you see if the drive, when you power on the PC, is making the noise that was coming from the TiVo.
There were, I think, 2 Premiere/Series 4 models whose model number began with TCD746, the TCD746320 and the TCD746500, which was a later release and was really just a TCD746320 with a 500GB hard drive instead of a 320GB one.
An image from the TCD746320 needs to be restored, or copied, to a drive which is at least 320GB, and an image from a TCD746500 needs to go onto a drive at least 500GB in size.
Which means if you're using a 2TB replacement, either will work.
Any 746 image that comes from a different 746, even if it's another 746320, will have a different TiVo Service Number recorded in it wherever it is that it gets recorded, so when the TiVo boots up from that new image, the first thing it's going to want to do is change that, which it's designed to do. It'll put some sort of complaint on the screen and tell you to leave it plugged in and leave it alone for awhile.
That's why you can't move a drive from one TiVo to another and save the shows the first one recorded, because those recordings are tied to the TSN of the machine which made them, so they'll only even be acknowledged to exist on the drive by that particular TiVo.
If I were in your shoes I'd put the "bad" drive in the freezer overnight (or until you're ready to try to copy it) and figure out a way to keep it from getting hot during the copy process and use
to copy it to another drive of equal or greater size, keeping in mind that you'll probably only get one shot at successfully doing so.
Before you put that 2TB into service, by the way, you need to run the manufacturer's own diagnostic software long test on it, just to be sure.
After that, you could, just as a test that the only problem is the original drive, copy the drive from the other Premiere (assuming its model number also starts with 746) to that 2TB (don't bother with expanding at this point), and put it in the sick one and see if it works once it resolves the TSN mismatch.
Copying the original drive to the 2TB will overwrite that other TiVo's image on that 2TB drive, so that won't be a problem.
If you copy the original drive to another, physically healthy drive, then when it boots up in the TiVo, maybe the TiVo will be able to fix the scrambled software problems. If not, you'll need a 746 image from somewhere.
