Shouldn't that be "Re One of Richard's questions:"? :o) Regards, Richard Schuh

DMSPLU and friends tamper with the timestamp of a single file (and cause the directory to be written as well). I don't think you could use them to modify these two special files at the start of the directory (we are actually looking at the timestamp of the special file that maps the directory blocks). But if you have the disk linked R/W and not accessed, you can do whatever you like reading and writing blocks to fool us. I suppose that CMS uses the timestamp to invalidate the FST in DCSS (but I did not check the code). Rob
