To me, that's an irregular disklabel layout. Please read disklabel(8) manpage. I have never dealt with any drive with a single 'c' partition like yours. I think this is dangerous. I also think that your data may be screwed up there, but I'm no expert. If I'm wrong, your disk should mount fine (i.e. mount /dev/ad1c /whatever should work). If I'm right, you may have to hack a bit further to restore your drive. At any rate, make backups (if you can). Dump might be able to extract the data from the raw disk (ad1c). Then you repartition with /stand/sysinstall and restore the drive. Another thing... Your 'disk:' field in disklabel output should be more like: disk: ad1 or something like that. 'amnesiac' is a good hint that something's wrong. Also, you mentionned that fdisk output says that your FBSD slice is the 4th on the disk. Maybe that you should try: disklabel ad1s4... Just disgressing... A. On Wed, 8 Nov 2000, Noor Dawod wrote: > Hi all, > > I apologize if this is the wrong place to ask such questions.
