Schedule and guide data is not stored on the drives/HDD. “Old” units were 4-tunsers while all Tablo Quads have always supported internal drives. – “Nope. Same # of tuners. Just a newer ‘fancier’ name.”
You might try moving your drive to new tablo - https://support.tablotv.com/hc/en-us/articles/213345486. It first backs-up the internal DB to the drive. When a factory fresh tablo finds it on the drive it restores it.
Of course it’ll also restore all the references to the current recordings on the disk. If you don’t plan to copy the files to the new internal drive, it’ll be annoying until overnight maintenance mode supposedly cleans things up.
Note, this process if for external drives. I’m suggesting you may use the process partially to transfer your “guide data” …tablo settings, schedule and stuff.
It’ll just have a reference to the recordings, obviously these aren’t on the new internal drive, so you can’t play them. Unless, maybe you delete them first (so they wouldn’t show up), but if you plan to keep your old one in service until you watch them… well that’s not going to work.
Again, this isn’t a supported process, but it’s possible it’ll get you where you want to be.
I’d like to see them surpass Tivo and come up with a way better Tablo model
