Did you try working with a sector size of 2048? (-S parameter on mkdosfs)
I know a lot of devices (like MO disks and most DVD-RAM) work with 2k sectors
rather than 512 as is the default assumption a lot of times. If you do a
mke2fs (ext2 rather than (v)fat) its the -b 2048 that solves your issue. I
haven't tried a -S yet but from the man page of mkdosfs that should the
same...
