        Hello.  I'm not sure if this is a related issue or not.  I'm not
seeing filesystem corruption in the sense that fsck doesn't pass the
filesystem after a change.  What I'm seeing is that the files on the
filesystem do not contain the d
ata which they're supposed to. this  applies to both MSDOS and FFS filesystems connected via USB. In the MSDOS  case, I
can get the corect results by not having two processes write to the
filesystem at once.


Ah, I see -- it looks like what 
I've seen is not related to your  observations.

Can you confirm that your USB device is reliable?

For example can yo
u write verifiable data to the raw device and read  it all back reliably and repeatedly?
