repost: Incorrect superblock

[Dave]

Hello,
    Some urgency on this issue! Here's some additional details not sure the 
last msg went through.
Thanks.
Dave.

Hello,
    I've got a 10 gb ide drive that has critical data on one of it's
partitions /dev/ad1e. This drive was originally gmirrored in
another box it worked fine, it was the master drive. Now i've
installed this drive as a slave in another 6.0 box, and now it
shows up as ad1 with the partition i want being ad1e. I did a mount it 
worked fine. So i knew the drive was working, i then unmounted the 
partition, and tried to dump it to another drive. This didn't work, dump got 
an error about incorrect superblock. I then did a mount
-o ro /dev/ad1e /mnt and i'm getting an error "Incorrect
superblock" from mount. I then tried fsck /dev/ad1e and got the
same error msg. These partitions were formatted with ufs2 as their
filesystem. I then ran bsdlabel ad1 and got a printout of my label,
this showed up which gives me hope that this data can be retrieved.
An error i'm getting from bsdlabel says that the c: partition does not cover 
the
> entire disk and that may result in utilities not working correctly. Any 
> help appreciated.
    Some urgency!
Dave.
