Unfortunately when you have multiple disks of different types, like you do,
there's no perfect way to figure out what number will the bios assign to
each one.  It'll be possible to improve this in the future (by not using
the bios), but this will take time.

The solution for these situations is to edit device.map.

Error handling in the scripting engine clearly can be improved.  I'll keep
this bug open for that purpose.

Thanks
