> Really? fsck can recover from losing 4K bytes surrounding the last > metadata block written? The only metadata that matter are the inodes and (for ffs) the indirect blocks. You do really want the latter to be single disk blocks - many systems actually write them synchonously. The inode is (probably) only 128 bytes, losing an inode block will lose the other files. A journaling filesystem probably already has ways around this...
