Tried other disk management software on my computer woitn Win10 OS on it, program could not find the HDD's.
Stumbled on to AOEI HDD manager, after some general clean-up of 90 gigs of unwanted stuff, ran the program, worked like a champ. Merged the D partion into the C drive liked I had hoped it would.
