Used to be one of the three biggest names in the micro world?) used a sector allocation similar to AmigaDOS, with the added benefit of having a section of a disk that held all the directory entries. Ugly, slow and fragile. TRSDOS has (had?) the same problems. But for a real laugh, take a look at the early (and possibly still in use) Series 1 file systems. >Well I'm saying it.... the 4.2 BSD filesystem is fast, efficient, and one >of my favorites. You could fit most of its concepts in a file-system >fit for the Amiga. Fast? Efficient? Uh, then why is namei caching so high on the list of things that make 4.3 run fast? You should be able to make it fit into an Amiga; after all, MicroWare got most of the v7 file system into a CoCo. But it's not clear you want to take a 10+ year old file system design (the basics of the 4.2 FFS are still Unix), as opposed to try and incorporate some of the things that have been done since then. The file/block headers are a move in that direction; not perfect, for some things not as good as a Unix FS with the same lack of caching (I hope nobody ever really tried that!); but like I said before - it's nice to see the micro world exposed to soem of these things.
