I may have mentioned restoring root directory using peek/poke commands of a primitive boot loader. Right before Comdex (fall 1981) someone accidentally wiped out the root dir. IIRC we had just two systems that actually worked. The other person was copying the floppy to the second system when something went wrong. The backup didn't work. And this was a Comdex special filesystem (with demos for the show painstakingly put together and no time to recreate it all from scratch). I happened to remember inode & block numbers of the first few things so I fixed up the root dir enough for the system to come up & run fsck. Luckily very little was lost and we were able to repair the demos and run them at Comdex!
