Raaf,
What's the size of the memory stick? Is it 32MB like Dennis has?
The check for the field that affected you isn't critical to msdosfs'
operation, but the field itself is specified to be non-zero.
Konstantin, is it alright to remove this field?

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.
