Re: Unable to mount ufs drive after changing drive order
SOLVED. I removed all entries in fstab except my root and swap. Then removed the entries for the swapped drives from /dev... and rebooted. Once the machine came back up I was able to run fsck on the drives with their new numbers and mount them without issue (using the same commands as I had tried earlier). Not sure why this worked but I am happy to get my data back. Hope this helps someone.

Unable to mount ufs drive after changing drive order
I have a FreeBSD 4.9 machine (i386) with 3 hard drives in it.
