Problem mounting Data harddisk of FreeNAS

[iwonder]

I have a pc for learning. On which, I have winxp and fedora 10 on a 250G sata harddisk.
Recently, I installed FreeNAS on USB-key and added to this pc another 1T sata harddisk for main storage. This new harddisk is formatted by FreeNAS, option called UFS. I don't exactly know what format it is cause reading more just get me more confused about EFI/GPT/ufs/nfs/... at this moment.

My problem is when I boot Fedora 10, I can't mount the 1T sata. And so, no music.

I have created a directory /mnt/big and tried "mount"

[root@linux fs]# mount -t ufs /dev/sdb1 /mnt/big
mount: wrong fs type, bad option, bad superblock on /dev/sdb1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

Suggested reading or keywords for google are also very much welcome.
Many thanks


fyi
fdisk -l gives me the following

[root@linux fs]# fdisk -l

Strange that I steal a line from ubuntu and it works for read-only mode.

$ mount -t ufs -r -o ufstype=ufs2 /dev/sdb1 /mnt/big


p.s. I also installed the latest filesystem-xxxx.ppc.rpm found on rpmfind.net (search key: systemfile ufs), not sure if it is a must.
