Ubuntu – Newly created ubuntu users cannot access the internal hdd partitions

I have a problem with my ubuntu 11.10, the issue is described in the following link: Hard disk icon disappears after mounting

After digging and digging I found the issue. It's a problem with ext4 partition, because I'm able to mount my NTFS partitions without any issue.

Here are the details.

My question is how to mount ext4 as same as NTFS ?
