W541 Ultrabay usage

[josh5k]

I just picked an used W541 and was looking to replace the Ultrabay (it's empty right) with a Second Hard Drive caddy. The space looks to be sealed with just a placeholder plastic and it's not coming off prying with a screwdriver. Is it safe to pull it off or would there perhaps be any screws that I'll have to remove first? (Haven't found this in the Maintenance manual).

Also can I use any regular 9.5mm caddy or should I look for an Old Lenovo part specifically? I've had good luck with regular caddies on the T420 or prior but the 541 looks to be not as well constructed as the prior generations and am looking to err on the side of caution.

I have one of these in my T440p (same as for W541).
They come with the proper cover.

Remove the big bottom cover, remove 1 screw on the mid-left of the HDD/SSD to pull out the Optical drive/dummy.

Thank you RBS. Will first try to find that part around here and then go about removing the dummy plate. Will update once done.

Now to find a decent m2 2242 for a third SSD

I'm using 2 of the Transcend 2242 SSD drives in my machines and they work well. I'm about to install heatsinks on them as a precautionary measure.
