I might have to get a new hard drive for my Dual Lite Tablo. How would I move existing shows stored on the old drive to the new drive?
Search the forum, no official way but there is an unsupported method to do this.
I’ve just recently done this, I used Clondzilla Live. It takes care of everything all in one. Even has option if moving from smaller drive to bigger drive, one-time-deal.
As theuser86 points out - there are several post with step by step instructions.
Then migrated drive to new tablo and later cloned off to yet another bigger drive - Quad external drive to internal drive. Although this is unofficially unsupported, it’s relatively easy.
