Are you saying it can't read the disk at all, or that it can't read it when
you try to boot from it but it can when the operating system is running?

I'm assuming it's a FAT32 file system, in which case I would suggest doing a
Web search to find out how to read FAT32 under OSX, and how to make a bootable
disk for a mac.
