Hello Eric
In all cases that I have seen something like this it has come down to
either a driver or a configuration issue causing some overlap.
Can you give me some more info:
1) 32 blocks is reasonably small for a Yaffs partition. Not too small, but
still smaller than normal. That in itself should not be an issue. How many
files are there? How much free space is there before modifying the files?
2) Are the other partitions mounted at the same time or are they left
unmounted?

Charles
