I am new to Linux and to Ubuntu, I was wondering, I have two hard drives setup in SATA ports (non-raid, at least I don't think they are). I installed ubuntu unto the drives fresh without any previous versions or windows at all.

However when I got the Ubuntu 12.04 LTS working, all I see is 1 x 120 gigabyte harddrive.

Also, not sure if this is important or not, my hard drives are SSD. My computer specs are

Asus P9Z77-V-LK Nvidia Geforce GTX 660 TI Intel i5 3570k 3.4

/proc/partitions shows:

Any help would be greatly appreciated! Thanks

Another thing I noticed is, when i use gparted to locate my drives, it seems that sda1 is my second drive that I am not detecting when I boot up and my ubuntu + FAT Boot files are installed in sdb1
