Lost disklabel

[Patrick Hartling]

I have a machine that is running -current from October 10, 2002. It had been running fine for about two weeks--up until I had to reboot it. When it came back up, one of my disks apparently lost its disklabel.

Is there any way to recover a disklabel? If not, I'm willing to grovel the disk and try to reconstruct its disklabel (there is really only one partition on it that I need to get back, and its at the beginning of the disk), but disklabel(8) won't even let me try to make a new one. If I run 'disklabel -e da3s1', I get an error saying "ioctl DIOCGDINFO: Inappropriate ioctl for device". Running 'disklabel -r da3s1' gives a "bad magic pack number" error, which does not surprise me.

This is a "dangerously dedicated" disk with a single BIOS partition containing four FreeBSD partitions. I have a second identical disk in the machine. fdisk(8) gives the same information for each, so I don't think the BIOS partition is messed up. Is there something obvious that I'm missing about how to fix this problem?
