No idea if anybody can help with this but for years I've been using the the Arris Gateway with an external hard drive and last week the PVR appeared to clear itself of almost every recording except for a small fraction of what I had while still showing that the PVR was about as full (around 80%).

I realized that it was cause the PVR was not longer pulling from the external drive and, while troubleshooting that by going into the external drive in settings, I found that it was saying there was no drive connected. I verified that it was connected and powered up, so I decided to reboot both the PVR and Drive. Once I did that, the PVR recognized that there was a drive but that it required reformatting. It will not use it till I've done that.

I have hundreds of hours of recordings on it and reformatting will require me to wipe that clean. Does anybody know how I can correct this without doing that. If not, is there a way I can back up what's on the drive so I can restore it once I've reformatted the drive?
