Why does my external drive mount as not writable?

I've got a 1 TB external WD drive formatted as Mac OS Extended. After upgrading my MacBook Pro this drive occasionally is mounted as read-only. If I open Disk Utility and Verify the volume, the verify completes without reporting any errors, and when it remounts the volume, it's writable again. Anyone else seen this behaviour?
