Hey guys, I totally misinterpreted @Lysander’s original post. I thought you were looking to transfer the recordings along with the schedule (even though your explicitly stated this wasn’t necessary). My bad!
So to correct myself, this is possible; all you need to do is remove the existing drive, attach the new one, and you’ll receive a prompt to format. The schedules are stored on the Tablo itself, not the drive. Hope this helps.
So, your upcoming shows will simply be sent to the new drive. The only thing that may cause confusion is the recordings stored on the original drive will still appear in the Recordings menu, but will not be accessible as the original drive isn’t attached.
