I would like to continue to use my old drive (C: after I have cloned it to an external drive connected to computer through an external box via firewire. The cloning software guidance suggests that you should remove the old drive after cloning. I would rather put the newly cloned drive on the shelf rather than remove the existing (and functioning ) drive and replacing with the newly cloned drive. Placing the new cloned drive on the shelf would provide a hot swap drive in the event of a non-bootable C-drive (a situation that has happen several times in the last month). Can you provide guidance. Thanks.
