Have you run e2fsck to clean up the file system corruption?  If you
have, do you continually get these errors afterwards?

You say this is an external USB disk; is there any possibility of the
disk getting unmounted uncleanly due to the cable getting pulled out
while the disk is still mounted, and then the disk getting remounted
w/o having e2fsck run on the disk?
