The RioCar doesn't properly start up with only this Toshiba as master, so I cannot get to the stage where I could use Emplode to install an upgrade image. Once the RioCar says "No hard disk found", it's game over for doing anything with the Toshiba hard disk.

Too bad the disk builder doesn't stress test BOTH hard disks - maybe that would provided a clue to the real cause of the problem...

What I am wondering is whether anyone else has been able to use this particular model successfully in a RioCar.
