I have two VIP211K, one with a 1TB drive, the other with a 2TB drive. The 1TB one works fine has over 150 recordings. The 2TB one cannot use the whole drive, when at an undefined limit will show recording and then show saved , but the file is nowhere in the list of recordings. If you are watching while recording over the limit, at approx every 10 sec the picture and sound go blank momentarily. If I erase files, recording works fine until I hit the limit again, I don't know if there are too many recordings or no more disk space, or a bug in the receiver software. The receiver shows many hours available for HD recording. This has been going on for years. There have been receiver updates, but the problem is still there. I formatted the drive on the VIP211K. Does the wally have the same problem with a 2TB hard drive?
