I have a 500 Gb EHD connected to my VIP622, it was getting full, I wanted to go to 1Tb and give my Daughter the 500Gb for use on her 211k. I have successfully cloned the 500Gb EHD to a 1Tb EHD and the 622 sees it as a 1Tb drive. The program I used was Acronis which I use for backing up an entire hard drive and cloning an old hard drive to a new one. It is a great program and useful for a lot of disk related activities. You could also just backup the EHD to a file if you wished. I don't know if it would work on the internal hard drive but it is worth a try. The cloning process took 4 hours but there was a lot of data and both drives were connected to the computer via USB. Cloning usually does not take that long when one or both drives are connected internally or one internal and one USB. But the important thing is that it worked and I now have a functioning 1Tb EHD with the original data intact.
