Home Forums Mac Software Mac Operating Systems Weird Assorted Problems???

I'm at the Apple Store now. It says Snow Leopard cannot be installed on this disk. Please select a Time Machine or oner backup you wish to restore from. I don't understand. The external drive it wouldn't eject is off and disconnected and I zero'ed out the internal. There does not seem to be any reason I cannot reformat the internal drive as I did before, start over, because it seemed when I rebuilt it before perhaps sometime when I copied old files from the SilverKeeper backup, that disk and the internal one on the mac became linked. I don't know what that system folder was on the SilverKeeper drive, it was not a full system folder, nor was it an alias, the only visible items were internet files of some type...
