Media steaming from two Hard drives one p.c.

[Hicky]

Hi All My 1st post on any kind of Forum ..... I am using an old P.C. to store all my Media on and stream it through my Hisence TV. The P.C. has two hard drives on it a 500gb one C: which has my windows on etc and a 1tb drive . I can stream files no bother from the c; drive but can only see the folders and not the files when I put any content on the other disc drive. I have all the permissions etc set the same for both drives. I am running out of space on the C drive and want to utilize the other one. Any help much appreciated.
