Could possibly be a disk hardware problem.
Run this command as root to check (you may have to install smartmontools):
smartctl -a /dev/sda | more
You could also run a file system check.
If it crashes before you can do this, boot from a live CD/DVD (e.g. Gparted Live).

It's a USB attacjed disk so either your disk is heading towards the scrap pile and needs to be replaced or the USB socket/cable/enclosure are bad and need replacing.
The future appears to be RHEL or Debian. I think I'm going Debian.
Info for USB installs on http://wiki.centos.org/HowTos/InstallFromUSBkey
CentOS 5 and 6 are deadest, do not use them.
