Occasional beeping noise from My Passport for Mac

I purchased a My Passport for Mac external hd back in March.   About two months ago, it started making a beeping  noise and finally crashed.   WD support (who are wonderful) replaced the hd.   Now I’ve had this new hd for about two weeks and i noticed one beep from it this morning.   Seems to be fine.   Does anyone know if this is something to be concerned about?

First time that I heard about it. Are you sure is comming out of the drive.

I get a beeping noise too, definitely from the drive.  Time Machine backups fail when that is happening.  I’ve been rejecting and disconnecting the drive when I notice it happening.  When I reconnect it later, things work fine… for a while.
