I am not sure if this has already been covered, as there are various similar posts, so please accept my appologies if it has.


I have an external 1TB WD My Passport drive which I use for TM backup's.  When I plug in via USB, DriveUnlock appears.  I unlock the drive, then instigate a TM backup.  All goes fine, then from what I can gather, when the TM backup has finished, the drive ejects itself.  There is no error messages, unmount drive issues, it just dissappears from finder.  I can only assume the backup has been successful, as no error messages appear, meaning the drive wasn't ejected while backup was in progress.  I have changed the USB cable, as well as tried different ports, but the same always happens.  In System Preferencies/Energy Saver, I have made sure the Put HD to sleep is un ticked.  Still it happens.  Has anyone else had this problem, and is it fixable?  I would love to keep the drive attached and backing up for  the period I am working, usually 12 hours a day, rather than the once a day at the moment.
