I want to create hd image of iMac OSX 10.6.8 (Snow Leopard) to external usb by ccc 3.5.x CCC permits to choose as target: existing disk new disk image existing image disk remote Macintosh choose folder I chose existing disk for my external usb disk while among these 3 target options: temporarily archive modified and deleted items delete anything that doesn't exist on the source keep recent files, don't delete anything I chose temporarily archive modified and deleted items I noted no checkbox about 'boot' flag. Now I'd like to know: my usb disk is bootable ? if OSX was damaged, I can use usb disk to restore the whole OSX (included app+data) to original disk? You think it's better to create OSX image for my scope? I know Snow Leopard has no recovery partitions, so what tools can I use to restore CCC image to a new disk when I boot if internal disk has been replaced to new one?
