If your archive for frozen snapshots is on the ext usb hard drive and you boot up a frozen snapshot does the external hdd have to be on and connected to the usb port? Is it reading the info from the ext USB hdd to build the rebuild the frzn snapshot to pristine state? I tried booting up a frozen snapshot without the extnl hdd on or hooked up to the USB port and I noticed that my ICONS in my lower toolbar have changed order compared to when it was originally frozen. I though it was supposed to revert all back to original? I guess that means it needs to look at the ext usb hdd for info to rebuild to original? EDIT Problem solved by making sure my EXT usb hdd was hooked up when booting up a frozen snapshot.
