I am trying to install 12.04 amd64 on gateway laptop from an USB drive. The drive boots fine and I can use the live distro. But when I try to install it, it hangs and the small "terminal" pane bellow the status displays:

May 14 16:14:18 ubuntu kernel: [  891.776455] sd 6:0:0:0: [sdc] Asking for cache data failed
May 14 16:14:18 ubuntu kernel: [  891.776462] sd 6:0:0:0: [sdc] Assuming drive cache: write through

The funny thing is I am trying to install to sda4 and sdc is the USB drive.

Over and over again

The full output is :
