I searched for all day but no Seagate firmware update available (attempt to update shows it to be current) and no other help available from Seagate "support." Can anybody help me cuz I'm really in need of the files on this drive? I can see the light on HD so I am sure it is getting power. Since I upgrade to Yosemite (maybe coincidental?) the HD is no longer recognized by my MacBook Pro. I use a Seagate 2TB Backup Plus Portable HD as my Time Machine backups drive and it had been working fine.
