I just had my root file system superblock trashed again. I haven't had any msdos stuff mounted for several days now, either. I needed to reboot so I could run dos for a minute, so I shutdown to single user mode, unmounted everything, then ran fsck to verify that all of my superblocks were still good. Everything was fine, so I rebooted and started dos for about 5 minutes, then I tried to reboot FreeBSD. My root superblock was trashed again at this point. No, it wasn't DOS, since the other times it happened, DOS never entered the picture. A quick look showed that most of the superblock was zeroed out (maybe the first 1024 bytes). I've got to go install some hardware for a customer right now, but I'll verify exactly how much data was munged when I get home later, and see if I can figure out what the few non-zero bytes might have been. BTW, fsck core dumped on me with this superblock - floating point exception. Probably doing some divide by zero with the bad data. I had to use the "-b" option to tell it where to find a good superblock. -- Mike Pritchard mpp@mpp.minn.net "Go that way. Really fast. If something gets in your way, turn"
