Thanks for your help Andrew. I'm not sure if I did something wrong, but
I'm having some problems...

Look at:
mdadm -E /dev/hdc
If it has a superblock, zero it with 'mdadm --zero-superblock /dev/hdc'
> Same for hdg
I did this, rebooted and the system wouldn't reboot. Yikes! I was
however able to boot with giving root=/dev/hdc2 to the kernel.
Do you have any idea about what's going on? Thanks.
BTW, I don't have a /dev/raidtab file.
Here's the relevant part of dmesg:
