Per What's a reliable method to create a stand alone recovery disk for Lion?, I'm attempting to create a two-partition thumbdrive such that one of the partitions is the Recovery Disk created by Recovery Disk Assistant and the other partition enables me to use the rest of the space for storage. Since I want this storage to be Windows 7/XP-compatible, its format will be MS-DOS(FAT).
So far, my attempts have been thwarted.
When booting my Mac with the thumbdrive inserted, I can select the drive but that only ever results in a gray screen. I have enabled FileVault 2 on this machine, if that matters.
What magic do I need to get a working external Recovery Disk on my thumbdrive?
