What determines what is physical disk 0 vs physical disk 1? On a system with 1 hard drive and 1 usb stick is the usb guaranteed to be physical disk 1?

The computers BIOS and its OS determine which order the disks will appear in. For example if you have 3 hard disks in your computer, they will ussually be ordered 0,1,2 starting at the lowest port number they are connected too. However, if you change the boot sequence in your BIOS any of the hard disks could be moved to position 0. So the long story short, there is no way to know 100% which is which. Ive added some details about the disks into the later versions of my apps so you can determine which disk it is. Perhaps in the future ill add serial number functionality etc to determine it 100% correctly.

In Windows, you can use the Disk Management utility to view the Disk # assignments (found in the Computer Management administrative tool).
