Most hard drives are quite sensitive to shocks, and will rapidly fail when used on a moving vehicle. The 4 Gb drive you mention is not likely to last long unless it's one of the new "hardened" (read "expensive") drives. In fact, I seem to recall that one of the HD companies (up the road from here, in Longmont) just announced that they were developing
the first HD hardened for vehicular use, to be available "sometime next year."
