I have a vip722 with a 750 GB external HDD that is practically full. This evening I went to play something and the "My Media" list was blank! I unplugged the power and USB cord and replugged to reset the unit and it was very noisy. I did get my programs back (for now) but I'm practically certain that the EHD is very close to going bad. I plan to buy a new 1 TB EHD tomorrow. Can I easily clone my existing EHD programming to a new EHD? I know of course that I can transfer the programming to the DVR and then onto the new EHD, but that will take several sessions and many hours. I've never looked at the file system on the EHD that is hooked into the 722. I'm thinking that I will see several proprietary files, or is there one large file? If there are several files the ideal situation will be the ability to copy the individual files to a folder on my desktop machine and then move them to the new EHD. I have enough internal/external storage capacity to move a large e.g., 700 GB file but it will mean moving some stuff around. Has anyone tried moving program files from a 722 EHD to a new HDD? Will I need to hook it into the DVR first to have the DVR format the HDD to its proprietary file system? Thanks for your help.
