if you lose that SDHC card, and someone finds it, you will not be seeing that again, despite putting your name and address on it.
Ditch the FAT/NTFS portion and concentrate onmaking the Mac OS X extended side bootable, not an easy task in itself
I have an SDHC card that I'm trying to make Mac OS X-bootable, but with an additional FAT or NTFS partition. The FAT or NTFS partition (it doesn't matter which) is only there to store a file with contact information if I lose the card. That way, if someone running Windows finds the card, they can pop it in and see my contact info. I haven't been able to get Windows to recognize its partition. Is this even possible, or does the GUID partitioning scheme prevent Windows from recognizing the volume?
