Thank you, downloading now.
I've seen it both ways:
1. Says there is no partition.
2. Says there is a partition, but it isn't recognized as any known type.
I agree that it is still worthwhile trying doing a DVRBars on both drives. This is just odd.
If the drive layout is being stored in flash memory, it would definitely make it less likely that it will be possible to upgrade a "used" system and preserve the recordings. I am tempted to say that it makes it extremely unlikely.
It may be possible to replace a failing drive by copying it to a drive with the exact same geometry but who knows. I am not hopeful
Odd, they worked before. Thanks for pointing that out. I'll figure it out, then edit the posts.
Does copying an expander drive and replacing it work or does it check the drive serial number? If it doesn't work, I doubt copying the internal drive will work either. If it does, then copying the internal drive might work.
If I had to guess on how the Roamio is set up, it's probably based on the Mini design, with the software, settings and meta data stored on a flash drive. The difference being in the Roamio there's a hard drive to store recordings.
I tried this but it didnt work, I selected the drive and when I did it came back with a error saying "NO USEABLE HARD DRIVES FOUND" even though it was listed.
I deleted the prior posts with the bad links and here's the corrected version:
Here's the thread for DVRBARS:

Here's the author:
PM him about how to get the image uploaded to him. I asked him to invite me to open a free Dropbox account (which is 2GB), and because it was by referral, by accepting the invite it got us each a bonus 500MB, for a total of 2.5GB. I was able to fit two 2TB full backups in that space, with plenty to spare, because the already small images zip compress down well.
For the drive you will be doing this with, the "after installation" image size will get bigger and bigger if you let it run beyond the required setup. So, once you've tackled the "before", you might want to take this into consideration for the "after" backup image.
Thank you for all that you have contributed, and continue to contribute. It is appreciated.
ok wil do. And use the hard drive that was never setup correct?
Thats really weird. I went in the other room and looked at one of my Premiere drives that is the original drive I have stored away, and it shows all the partitions, just to make sure I was telling you right, and it showed them all. I havent run into this before, very odd.
Well thank you for trying.
It would probably help to have both as a comparison.
Yes, that's the "before" drive for a before & after comparison.
Plus, just in case it's not blank, you will have a backup of it.
The author should be able to make a definitive determination, once he gets a copy and has time to pour over the results.
As a general rule no unless TiVo changed their partition structure. Since all the tools used so far cannot see the partition structure, I suspect TiVo may still use an APM like partition layout. Can try using pdisk on the MFS live CD . If it reads it then it is an APM like layout. The only definite way to read it would be using some hex editor tool like HxD or iBored. DvrBars full backup mode will copy the whole structure to a vhd file which then can be examined without worry of damaging a good image.
I sort of agree with here, but to be perfectly safe he shouldn't even be hooking them up to a PC. Until he or someone else verifies that everything works and he can at least record something (ideally filling up the disk) with no problems, he should put them away just in case.
You do realize that you are exhibiting at least as much impatience as anyone else? It's just that your particular priority is DVRBars.
THANK YOU, for posting something that actually helps corroborate what I've been trying to communicate for two days now.
If you go a few pages back, and work forward, you'll find repeated instances of me saying that the owner will benefit, as the first thing to come out of using DVRBARS in Full Backup mode, is a Back Up copy for them.
It's only when it comes to getting it to the author to analyze that it is of any other benefit, to anybody.
Is that 2 tuner model premiere or a 4 tuner model. The 4 tuner models have a modified APM with data found in areas that are normally reserved sections of each APM partition entry. Just speculating, but if Tivo carried that change through to the Roamio and because of the change, that program won't read a nonstandard APM entry, then that might explain the error....... or not.
It was a 2 tuner Premiere that I dont have in service anymore. I just unplugged it and havent messed with it, and the original drive I havent put back in it yet, so I thought I would take a look at it.
The 320GB model.
Ok, I can see that, and I concede that backing them up should have come first if he was going to proceed with the analysis, but you'll have to admit that the safest thing (besides never doing the R&R) is to put them aside until more is known about the upgrade.
I'll admit that, only with the addition that the SAFEST thing is not to even mess around with it at all (there's risk from the moment you open the case).
Now that he knows the risks, it's up to him. He's already poked and prodded with other tools, so that cat is kinda out of the bag already...
This is a catch-22, where you can say it's safest to know more first, but if everybody did that, what would we ever know...
I am interested to see if the CableCARD pairing is also stored in the Flash memory, making drive swaps that much easier.
