The Achilles' heel of all USB-driven external hard drives is that they push your laptop's power capabilities to the limit: even slight brownouts become extremely likely, making data corruption inevitable, and Microsoft complicates matters further by assuming it should run chkdsk for you whenever it likes -- even when low power conditions guarantee both a chkdsk fail and the corruption of the very data the utility is trying to 'save' for you. Not sure why the real world and the Microsoft world have diverged so much here.
