Hi Norman, Thanks for asking as it never crossed my mind to verify with DiskUtility. As it turns out DiskUtility also falsely reports the USB volume as Bootable. I'm sure if I were to reformat the drive while in the USB case it would correctly report as not bootable. The drive was originally in a G4 Laptop where the bootblocks were configured to boot into the System on the drive (no longer there by the way). DiskUtility also pointed out it has the OS9 drivers installed. Both of these items I'm guessing hosed the results. In Apples order of checking I'm sure it checks early for USB devices and marks them as not bootable. Further down the process it checks for valid bootblocks or OS9 drivers and marks the volume as bootable. The results are only due to the fact that the volume is a Franken-Drive and would be configured completely different if it had not been in a Laptop previously.

So good news - use Charles devInfo.rb example for calling the ShellScript with confidence. I'd also bet somewhere in the bowels of the OS there is a list that could be tapped into to get this same info.

Does disk utility tell you this drive is not bootable ?
