Q3 : I'm not sure JBD can be used for FAT improvements. Do you
have any comments ?
I might not be the best person to answer this, but this just seems so
obvious:
If you plan to let a recently hot-unplugged device to be used in another
OS that doesn't understand your journaling extensions, your disk will be
corrupted.
If this is supposed to work only on OS's that understand your journaling
extensions, then there are much better filesystems out there with
journaling already.
You might be able to reduce the size of the time window where hot
removing the media will cause problems, like writting all the data first
and update the metadata in as few operations as possible. But that just
reduces the probability of data corruption. It doesn't eliminate it at all.
