Query: Beware: Works poorly with some tool-less bays

I purchased this bracket hoping to mount a 2.5" laptop hard drive in a conventional 3.5" bay in a desktop case. Initially it looked like it was going to work perfectly, as it did in the pictures but when I began to attach the bracket to my hard drive it immediately became apparent that my hard drives screw holes were not lining up with the slots on the rails. the rails were simply not long enough to accommodate the hard drive in any way. They were essentially useless.
