Mounting existing ext4 disk (internal)

[Tigerspill]

Hi,
I have FreeNAS running on my HP N54L.
I have a three disk ZFS volume created using the right most three disk slots (of four). This is all working fine.
I have a fourth disk which I have removed from my QNAP TS-210 and installed in the leftmost internal disk bay. I believe it is formatted as an ext4 filesystem.
Is there any way I can mount this disk and see the data already on it?
Thanks

Nope.. if you check the manual ext2 is all that is supported.
