  1. Hi! Nice tutorial and really helpful for an R510JK as well, since it’s the same layout.
    I’ve replaced the optical drive with an SSD + matching caddy. Unfortunately I couldn’t remove the face plate/bezel of the UJ8E2 in order to attach it to the caddy. Have you disassembled the face plate of the optical drive as well? Could you post some advice/pics on how to get it done?
    Thanks in advance.

  2. Awesome manuals David, thank you so much for providing all these. This one is also good for X550L/N too. I have had to replace keyboard due to a couple of key failures, no spills or anything, just dodgy I guess. I am looking at replacing the HD with an SSD and then placing the HD in a caddy as sprach has done above.

    Sprach, did you just copy the recovery partition onto external, then copy onto your SSD? How to start the computer if the SSD has nothing on it? I want the original recovery partition. How to do that? Where did you get your caddy? Any advice before I do this? Thanks 🙂

  3. Hi!
