I agree with your recap. When I run SGD 0.9799, I select Boot & Tools / Boot Master Boot Record (MBR) / Boot Master Boot Record (MBR) SGD lists two drives, (hd0), the laptop hard disk and (hd1) the USB drive. I select (hd1) and SGD displays: "Error 25: Disk Read Error" When I try to list the USB partitions, I select Boot & Tools / Show Partitions / Show Partitions SGD lists two drives, (hd0), the laptop hard disk and (hd1) the USB drive. I select (hd1) SGD displays the header for the table of partitions, but no partitions. For a "direct boot": I select Gnu/Linux Boot Gnu/Linux Boot Gnu/Linux Directly SGD boots the laptop hard disk.
