I changed my hard disk to Intel SSDSC2CW240A3 (240GB SSD) and want install Ubuntu. But Ubuntu can not recognize the SSD. So I install win7 first and retry from USB(remove win7 and install Ubuntu). But it can not recognize SSD either. Only get the picture at the installation type step (sdb is my USB stick and sda is the 240GB SSD):

I use gparted to delete all 3 partitions of SSD(sda) and build the SSD to ext4, then Ubuntu can use SSD to install.
I think the reason is the initial file system format or the partition of SSD.
