I've asked about this elsewhere but still not clear what to do. I am upgrading by putting a 1Tb WD10EADS Caviar Green HD and will place the old 320Gb drive in a USB caddy and run the recorded stuff that's there from the USB connection. My question is about the file structure best suited to do this. I suspect it will be sense to get rid of all the folders and simply have all the recordings as a single list. If I leave the folders in place I suspect their titles will not be readable. Am I right?
