Hard drive missing

If you insist going this path, here’s one option Recovering Show from good drive/dead tablo (via handbrake)

again, painful process.

And one use wroth a python script to extract the meta-data from the backup DB on the drive, then export the show… Extracting Videos from Tablo External Hard Drive

If I recall, it does one recording at a time… very tedious.

These options are more last-resorts, if you tablo pukes and you have a drive full of shows.
Best option would have been to transfer drive to new tablo.
