In addition to notification of failed recordings, you should have a notification that the hard drive is not showing to Tablo as connected. I went on a brief trip and missed three days of recordings. A simple restart fixed the issue. I could have called my wife and asked her to restart, but I didn’t know there was a problem. I’d say this would prevent more failed recording problems than the notification of failed recordings issue itself - particularly if the Tablo could detect a hard drive issue prior to recording. – so I’d make this a high priority over your other features. Many of your poor ratings have to do with issues like this, and it’s justified when a fix is pretty simple. You’ll have some issues with an early generation product, but doing things like this eases any pain.
Great product, BTW.
