USB disk with Lion recovery partition + storage partition shared by Mac & Windows: Windows can't read it.

Question

I have a Lexar Express Card flash drive (16GB). It works the same as any USB flash drive.
I use it to move files between Mac OS and Windows 7/Bootcamp: Drag files to it in one OS, reboot in the other OS, take the files back off.
Recently, I discovered the Lion Recvoery Disk Assistant, which allows you to create a Lion Recovery Disk on an external drive (just in case). So, I decided I would use a ~1GB partition on the express card for the recovery disk, and leave a ~15GB partition for the same file sharing I am used to.
This setup requires that the disk use a GUID Partition Map with a HFS+ file system for the recovery partition, and I use a FAT32 file system for the shared partition. The partitioning was done in Mac OS Disk Utility, and then I think the Recovery Disk Assistant modifies it further by adding an EFI partition.
When I try to access the disk in Windows 7, it says it needs to format the drive first (which it shows to be a ~200MB "volume" on a disk with ~15.4GB "capacity"). From what I have been able to find on my own, Windows 7 should be fine with a disk using a GUID Partition Map, and both OSs can use a FAT32 file system. So why does Windows only see the 200MB EFI partition at the first section of the disk, and not the other partitions, particularly the FAT32 file sharing partition?
The last thing I will mention is that the disk is being seen by Windows as a MBR/Master Boot Record partitioned device. I'm assuming this is the GPT/GUID Partition Table's protective partition's fault; the one MBR partition that keeps the GPT partitioning safe from software that doesn't recognize or know about GPT.
I'm asking on the Apple discussions because it's in Boot Camp and I'm primarily a Mac user. If anyone knows a better, Windows-focused place to ask, please say so!

You really need to search first as there are A LOT of post's with the same question. Different issues with different Models.
What model/year do you have and what OS were you using first? Snow Leopard (10.6) is the last one that came with a CD/DVD with the computer.
You insert the disk when it's done installing W7 and reboots into Windows then you insert the 10.6 MacOS Installer disk for the Windows drivers. Lion does it a different way.

Lion (10.7) is only a download now, there are no more physical disk's, (unless you pay the extra money for the USB installer thumb drive directly from Apple). So if your computer came with 10.7 Lion installed then you will not have a physical disk. There should be a "Repair Partition" that you use to boot to if you need to  repair or to reinstall the Lion OS.

Please Help!
Thank You!!!
I don't believe the Boot Camps drivers are in the Lion download anymore, ( to keep the download smaller?), the only way you get them now is when you start BCAssistant, it will prompt you to download them onto a CD, or USB drive. You have to download and install the Boot Camp drivers separately. You then insert it when it's done, when Windows boots.
