My legacy tablo did not record yesterday’s Y&R and was not going to record today’s either,until I reset everything. It said it failed because of no storage. it has plenty of storage. It has an external storage drive-- WD Easystore with 1000GB. it never gets full.
I am not surprised that you had to reset. I had a similar weird situation a few months ago where the Legacy was telling me “no tuners available” (only 2 of the 4 tuners were functioning). A restart fixed it, but to be fair it was probably running for at least a year straight before the issue occurred.
The ad for the WD easystore says it has 1TB of storage.
