G5, 10.5.8 I've got my HD bootably cloned with superduper on two separate connected external drives. I can see them mounted on my desktop and SD can still clone to them. However I went to boot into one of them using the option key method, but I could not. So I checked the start up disk option on the preferences and for some reason the mac will not see either of the bootable clones, which it always has up until now and I do not know why. In the disk start up window there is a network device with a ? mark on it but both the HDs with the bootable clone are plugged in directly to my mac. I'm at a loss as to what the reason could be for the non appearance of the clones. Any suggestions appreciated.
