Well, had the same problem.
For me, it looks like SE is using FAT12 (!!!Not 16!!!) on a devive
larger than 32MB. Could have something slipped off my mind, but quite
close. It is a BROKEN msdosfs on a stick.
Just re-formated 1Gb flash with FAT32 using card reader and both K750i
and FreeBSD are happy.

Hi, i got a Sony Ericsson mobile phone that came with a pre-formatted
memory stick that i'm unable to mount in FreeBSD (it mounts fine in
Linux).
After investigating i found out that the FreeBSD msdsofs driver bails
out on the following code (the pmp->pm_Heads being zero):
----------------------------------
if (!pmp->pm_BytesPerSec || !SecPerClust
|| !pmp->pm_Heads
#ifdef PC98
|| !pmp->pm_SecPerTrack || pmp->pm_SecPerTrack > 255) {
#else
|| !pmp->pm_SecPerTrack || pmp->pm_SecPerTrack > 63) {
#endif
error = EINVAL;
goto error_exit;
}
----------------------------------
Removing the check for pmp->pm_Heads fixes it for me.
Is the check for pmp->pm_Heads really necessary?
Grepping through the msdosfs sources i can only see it being used for
validation and not used in any calculation (the same applies for the
pmp->pm_SecPerTrack value)
