I've done this three times with same results. Maybe there is enough info here to chase down this gremlin.
The NTFS (a proprietary journaling file system developed by Microsoft) support under linux is limited. These errors appears because the linux not able to fix the errors what can be after "unsafe" remove (or power fail, or else). Try the same with EXT4 or EXFAT formatted drives, and you wont get that errors (another story). Maybe the NTFS support will be improved... but for a linux OS, a linux file system (EXT4) is the best and safe choise.
