I have a Airport Extreme 802.11 AC with a LaCle 3 Gig hard drive attached by USB. I have an iMac and a Macbook Pro that I want to backup. I often receive cannot find backup disk error message when backing up with either machine. Most of the time unplugging and then plugging back in the USB cable solves the problem until the next backup. This happens on both machines.
