Still I doubt that it was softupdates that caused the problem. Softupdates does not chage the disk label. It changes some flags in the file system superblock. I suspect that what you realy have is a drive failure. It is time to get a new drive and restore from your dumps You do have file system dumps don't you? If you want to try recovering the disk you might try the following. Using /stand/sysinstall see if you can re-label the failed drive If that succeeds then try to fsck the drive If that succeeds then try to mount it if that succeeds make a back up and recover it to a new drive.
