We have a serious problem with a currupted TFAT partition on a StartaFlash
file system with our device. The flash disk probably got corrupted due to a
power loss, but then Windows CE does not start up again.

Any ideas, what we can do, since we have a headless system and need to boot
under all circumstances, even with autoformat.

In QFE 040311_KB837276 (Transaction status may become inconsistent when
power loss occurs while mounting TFAT partition on HDD. File Allocation
Table corruption may also occur) probably a similar problem seems to be
addressed. But even with the Q1/2004 QFEs installed we get the problem.

For details see debug trace below:
