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 data 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. -Brian On Apr 15, 11:16am, "Greg A.
