That's kind of strange as I can mount and read > /tmp/winfile.iso and it seems to be in good order. That is perfectly normal, an ISO file is an ISO-9660 filesystem image, it does not contain a MBR-style partition table. You can try to mount /dev/sdb itself. But you are probably doing something wrong in the first place. What is your endgame? Regards, -- Nicolas George
