This is a simple program which might help get some of the missing information.

I had to do something like this just this past weekend, and disklabel pretty much worked for me. You may be this problem due to having a "dangerously dedicated" hard disk. (note that I'm running a more recent snapshot of -current, so maybe my system has some changes that yours is missing). -- Garance Alistair Drosehn = gad@gilead.netel.rpi.edu Senior Systems Programmer or gad@freebsd.org Rensselaer Polytechnic Institute or drosih@rpi.edu To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
