Review on CJESLNA 2nd HDD Caddy for 12.7mm Universal CD/DVD-ROM - Optimize Your Search! by Tabish Jadhav

A few weeks ago I decided to add a second hard drive to my laptop and I am very happy with my decision. I never use a CD drive anyway, and it's nice to be able to store all my files on a second drive. This will make things a lot easier the next time I need a new computer. This container arrived in good/new condition and fits my hard drive and laptop perfectly. Note the 12.77mm; There are laptops with a smaller CD that require a different tray size. To insert a hard drive, you must screw it in from below; Luckily there were four screws. Even if you don't have a small screwdriver, the cart comes with one too! The only problem was that the instructions came with the cart; they were confusing and proved wrong. You didn't mention screwing in the hard drive; Instead, they referred to a "latch" that could be used to hold the disk in place. Unfortunately this trolley does not have a lock and instructions must be made for another trolley. To use this you need to use screws. However, it was easy enough to understand how things fit together just by looking and trying. All in all a great purchase.
