As topic says. I installed a second hd in my laptop a few days ago. Windows assigned it a letter and I put some files I wanted to backup on it. Today I turned on the computer and the second hd is not under my computer. When I go to manage by right clicking on my computer the second hd is there but there isn't a letter assigned to it, and I cannot do anything to the hd by right clicking on it. Is there anyway to fix this? I tried google and it said to right click on the drive and assign a letter to it but all of the options are greyed out except help.
