I have a lifetimed 1TB Premiere that I’m in the process of selling. It hasn’t been plugged in for a few weeks, so I did updates this afternoon and then started a C&DE. So far, I’m at about 4 hours 20 minutes and counting. My suspicion is that the 'up to an hour' message is generic for the Premieres and that the 1GB drive is the time issue, but this seems an unusually long time. Granted, I don’t think I’ve ever wiped a 1TB unit and any unit that I did wipe was several software versions ago. Any thoughts?
