I have a problem like this also.
I have a server which runs FreeBSD 7.2 and i did update it to RELENG_8 but i can not see the data disk anymore.
If i put in an system disk with FreeBSD 6 or 7 or pcbsd then i can read the disk fine.
Or if i put the data disk into a server with 6, 7 or pcbsd i also can see the disk.
What can i do to make the drive useable in 8.
