yes,I tried TFAT.It`s more safe than FAT but also sometimes (much less
probability) crashed.
I developed an application that wrote file into NOR flash always and
plug out the battery.In this case,the OS sometimes stoped at the
process "filesys.exe" and can not startup any more.....
I want to create two partition one place my app and one leave for my
data(this area can be erased and wrote).So when the data partition
crashed ,OS can auto format the bad data partition by set "AutoFormat"
opition in the registry and the app partition is well.
Have you tried to enable TFAT file system? This should.
help (but still not in all situations) to survive the
sadden power off. Anyway it is bad h/w design when OS
does not receive any chance to power down correctly.
What would you expect if the system is powered off
somewhere in the mid of the flash block write or block
erase operation?

off,winCE OS offen could not be startup.With the debug message,there
was a exception by filesys.exe.Is the patition table corrupted?If so,
how can i prevent this? or how the OS can reformat the flash partion
automaticly if the partion table was corrupted?
Another question is that:how to creat two partions in the rest unused
nor flash? By default I can just see one partion :"NOR Flash".
