Hello all,

I'm really screwed up my server last week, now I'm giving up on the 5.x
series as a server for a while, so I've installed 4.9.  I took all my
backup files and placed them on a second harddrive in the system, hoping
to just mount that drive on the new 4.9 system and restore the necessary
files.  However, I cannot mount the filesystem.  From DiskLabel in
/stand/sysinstall, I can see that it is /dev/ad1s1d, but when I type:

mount /dev/ad1s1d /backup

I get an error:

mount: /dev/ad1s1d on /www: incorrect super block

I have tried inserting a, b, c, d, e, f, and g and get the same error.
Is there something I'm missing?  When I try to mount the drive in
/stand/sysinstall, I get an error about "Invalid Option".

Thanks in advance for the help.
