Management of flash by Win CE 5.00 filesystem

Hello,


I implemented a FMD to use FileSystem on a flash component.
It works fine but now I want to store important data in a file. So, I use
TFAT to prevent loss of data. I observed that sometime the FileSystem need
to erase a complete sector of the flash and this operation is long (between
0,2s and 0,5s) due to the component timing.

Is-it possible to predict when the FileSystem will have to erase a complete
sector ?
Is there any information available about the "garbage collector" of the
FileSystem ?
Is there an API available to order the FileSystem to erase now ?

Thank you for your help.

None of that information is available nor configurable. The FAL internals
are not documented and not available in source.

Thank you for your answer.

But in this case it means that I will never be sure of the time needed for
writing my data. If the power is lost during the sector erasing, data to
write will be lost ?
