Never happened before but in the last week or 2 my 1 TB WD external HD keeps unmounting and remounting.  Says that the disk wasn't unmounted properly.  I then click ok, then it remounts (All 3 partitions, one being time machine).  This goes on over and over again!  I was able to do a disk utility on the external (before it unmounted) and everything said ok with all 3 partitions.  This drive has been working problem free with time machine etc for a year.  All my OS Mac updates have been done.  Maybe one of them caused this?? 

Please help.

MacBook Pro, OS X Mavericks (10.9.4), 2.66 GHz Intel Core i7
