Size calculation wrong when vdi is on a FAT32 disk

[rzt]

Steps to reproduce:

1. Create a FAT32 partition
2. In VirtualBox, begin the new disk setup
3. Select fixed-size
4. Choose to put the vdi file on the FAT32 partition
5. Select any size (doesn't matter, but make it small for this test)
6. At the final screen, there is an error saying the vdi file is too big

The problem went away when I reformatted the partition as HFS.

I would guess the easiest fix is to notify the user that a HFS partition is required -- but do what you will.

How small ? Maximum possible filesize on a Fat partition is 4GB

The maximum file size on FAT is actually 2GB.
