Some Partitions on External Drive won't mount - El Capitan 10.11.16, MacBookPro 15" late 2011

Hello all,

My Seagate 3TB was working fine an earlier operating system and I finally upgraded to El Capitan and the drives would force mount on computer sleep (common problem apparently) and now the drive is mounting one partition (general, files I have saved), but will not mount the other two (one of which is my Time Machine partition).

Any one got ideas? Both on accessing my partition and stopping the force dismount on sleep issue?

Thanks for any help!
