However, in my experience with them, they seem almost to be accomplishing the opposite objective. Two or three times my system has locked up hard (while I was trying to hot-swap my modular bay - it didn't work. Scratch that idea.), and I had to do a hard reset. Each time, I have lost the latest data I was working on. (I haven't been successful yet in disabling soft updates - my system is all one big root filesystem - so I don't know how it behaves without them). Incidentally, before my switch to FreeBSD, I was running Linux (2.4 kernel) with an ext3 journaling filesystem, and anytime I had to do a hard reset, I never lost a byte of data AFAIK. What can I do? Would turning off softupdates (if I can figure out how - I tried dropping into single-user mode and doing a tunefs -n disable, but it seems like it had no effect, even after a reboot) help? Or is there something else I can do to my filesystem to have some more protection? For the time being I'm running 4-STABLE (if there's something in 5 that helps with this, go ahead and let me know - I'm planning to upgrade over spring break in March).
