Hi, You mention the deleted bit. This was only in use with yaffs version 1, and yaffs2 does not use a deleted bit any more. Are you really using yaffs1? If you're curious about how stuff works, check out the "How Yaffs Works" document: http://www.yaffs.net/files/yaffs.net/HowYaffsWorks.pdf It helped me understand quite a lot.
