CAUSE

This issue may occur if you do not stop the USB 2.0 storage device by using the Unplug or Eject Hardware feature before you unplug the device from your computer. If you do not stop the device before you unplug it from your computer, some files and folders that are cached by the file system and that are used to improve performance may be damaged.

When you stop a device before you unplug it, the cached information is flushed, and any pending input/output operations can finish correctly.
