Hi!

What size is it? Linux only supports vfat (FAT32) partitions with at most  
4GB files. A disc image can easily reach that.
If the problem is that, the bug is in the kernel, not in qemu. (Just try  
to copy it an ext2/3 partition. If is isn't possible, or its size differs,  
the bug has nothing to do with qemu.)

ps. ext2/3 is surely better than vfat for disc images, cause it supports  
holes
