Does it not physically fit in the same space as your old optical drive? If not, then you have the wrong one which would be strange because they are usually a standard generic shape.  If you find one that fits then you need to to remove the outer bracket from your optical drive and fit it on the caddy so it can be screwed into the laptop chassis. 
Dear all, I have the following issue: I have an Alienware 17 R1 with DVD rom. Now I would like to replace the dvd rom by a hard drive/ssd. Only, how can I fit it into the optical drive bay?   [IMAGE] As I understand, I will have to get a so-called caddy - only which one exactly? I have already got one, but I am afraid it is the wrong one - either doesn't fit, or I am doing something wrong?   [IMAGE][IMAGE] I am grateful for any hints on this - thank you!   Greetings,   Phil      
17 R1, how to fit in a HDD/SDD into the bay reserved for the ODD?
