I cannot recall having ever rendered a FreeBSD > system unbootable due to UFS/UFS2 problems after a power failure or I can confirm the opposite. I did really bad things with disk drives, including accidentally disconnecting SATA cable on working system that was doing lots of filesystem writes. NOTHING wrong happened. I always use softupdates, including / partition (which usually is my only partition anyway :) Once i have failed hardware which sometimes was writting rubbish to disk instead of proper data. after discovering this there was a bit mess but ONLY in files and directories i was writing to!!! fsck with manual attention repaired it all without problems. After fixing hardware problems and few files i used it without change. I can't count how many times i ended with completely unreadable ext2, ext3 and reiserfs filesystem, the last being really kind of destruction ;)
