I have a 500 GB external drive that I use with my Win 7 PC and Snow Leopard laptop. It has the following 4 partitions:
Leopard Installer (HFS+)
Snow Leopard Installer (HFS+)
1 and 3 contain Mac OS X install CD images in case of any problems, and 2 contains a bootable backup of my entire Mac. The last partition is the one I store movies, music and docs on. The PC recognizes only partition 4, while the Mac recognizes all 4, which
is perfect. All this is with the GUID Partition Table (GPT). But since its recognized on both Macs and PCs, I'm guessing it uses something like a hybrid MBR. I don't know what that means, but I remember having to do a lot adjustment to get it to play well
with both my computers.
However, I no longer needed the leopard installer, so I erased that partition using disk utility, and formatted it with exFAT, and then again with normal FAT, so that I could use it with my fonera. Now, the windows PC recognizes the FAT partition, but not the
NTFS one it used to. It shows up in Disk Management as Unallocated space, but EASEUS partition manager can read the files off it, and the Mac recognizes it fine.
Any ideas about what's wrong or how I can fix it?
Update, output from diskpart.exe:

The storage partition, which is 300 GB or so, isn't showing up in the list of partitions.
I need to advise that the Windows 7 also support GPT. Maybe the partition table is already corrupted.
Please back up the useful data and try to re-build partition table via some 3rd party disk utilities.
