There is no journal feature in FAT. it means FAT is corrupted well in
unexpected status.
Can you explain specifically what error will happen in case of keep writing ?
I think that MS consider also about this. maybe they think that
keeping access is better than changing RO type by one file is
corrupted.

for example, FAT is RW filesystem. and it is corrupted well by
unexpected status.
If so, user can not write FAT filesystem anytime while using linux
FAT.  there is no mehod except they should directly remount fat
parittion. well known linux user can do it only.
