I have two 500 GB disks that I have installed on my ubuntu 12 system, One is my main file system, and the other I partioned as a RAID disk in the ubuntu installation. I would like to remount the second disk so I can use it with Linux raid and view it on webmin. Right now it is not even being listed a mounted. I used the command

sudo lshw -C disk

and the output for the two disks is such:

I just re-ran the installer and everything is working fine now. Found a few forums that said my disk might be going, but seems fine to me.
