I set up a triple-boot system on my MBP (Early 2008) with OS X SL, ubuntu 9.10 and Windows 7 Home Premium. I have a 500GB Hard Drive, and allocated 100 GB for Mac OS X, 60 GB for Windows 7, 40 GB for ubuntu, and the remainder I formatted as FAT32 for storage to share between the three operating systems (to hold iTunes and iPhoto libraries, movies, etc). I use rEFIt as my bootloader, and all three operating systems happily load whenever I choose them to. The problem lies with the FAT32 storage partition. OS X recognizes it quite nicely and I use it regularly. Windows and ubuntu, however, do not mount it. What's more, Windows Disk Manager identifies the space as unallocated space. Does anybody have any suggestions as to how to address this? Also, I backed up the data on the storage volume and tried formatting it as NTFS and HFS+, and they still won't properly show. I use MacDrive 8 on the Windows side for access to Mac partitions.
