Trouble mounting an ext2fs partition

My FreeBSD 5.2.1-RELEASE box is being hosted remotely.

I switched from RH to FreeBSD. All my web files etc are on the second hdd in an ext2fs partition.

I have read numerous guides, manuals, etc, but have not found a solution for my problem.

I have compiled my kernel with the "option ext2fs".

Here is what happens if i try to mount the other hdd:
#mount_ext2fs /dev/ad2s2 /mnt
mount_ext2fs: /dev/ad2s2: Invalid argument

#mount -t ext2fs /dev/ad2s2 /mnt
ext2fs: /dev/ad2s2: Invalid argument
Here is all the information i could gather about the disks:

Boot message:

While entering fdisk i did get a message saying the geometry of my disk wasn't correct, and it would pick a better one. Could this be part of the problem?

Also I read that some versions of linux use "Magic Clusters" to create more hdd space on larger drives.

Please keep in mind i don't have physical access to the box, and only have access to FreeBSD.

Thanks in advance for any suggestions/advice.

Where is the directory on mount??
should be /mnt/"your new made directory"

mount -t ext2fs /dev/"your device" /mnt/"your directory"
