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 below 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 :

This looks like a low-level problem with the USB drive (sdc) not responding properly: the kernel tries several times, occasionally sending a reset, but nothing helps. –  deltab Jul 8 at 14:46
