For CD-R/DVD*R the last block written (or written several times) can be the superblock so sequential media will work just fine. No use for a garbage collector there ;) For flash media, the entire first segment/erase block can be used to store the superblock in; filling it up sequentially and when full, trigger the erase block wiping :) Idea?
