We have been using table with an old HP hard rive since April. It finally gave out this week, and we purchased a replacement (WD Elements, Basic Storage 1 TB).
I unplugged the old drive, plugged the new drive in, and Tablo formatted the drive.
None of the images for the shows were loading however, so I tried downloading guide data. This did not solve the problem. I also tried emptying the cache, and deleting all website data, disconnecting and reconnecting. This did not work either. As I didn’t find anything searching these forums I started writing this post, and went to grab a screen shot. Fortunately the images do seem to begin to be being downloaded now. Perhaps this will be a useful experience to have documented for other users that might experience the same problem. (Perhaps it is our slower rural Internet.)
Unfortunately the Tablo still thinks my shows recorded on the failed drive are on the new drive. How do I make Tablo “forget” that old hard drive? It had about 600 GB of shows on it, so we were looking forward a bit to a clutter free drive for a while – a small consolation for losing our shows to the failed drive.
