WD Ultrastar DC HC550 18TB underside hole layout

Featured Replies

Hello :)
I hope someone can help me.
I`m thinking of getting some
WD Ultrastar DC HC550 drives, but I cant find any pictures or info about the hole layout on the underside of the drive.
I ask because I have an older fractal design Define XL R2 case and the WD Red 10TB has the holes spaced out too much for the drive bay  caddies to only be able to use 2 screws, so I want to know if I can mount the 18TB with all 4 screws or not.

Thanks :)

Here is the underside of a white label HC550 (WD180EDGZ)

So its missing the middle screws on the bottom too, meaning it wont fit with 4 screws on the R2 brackets :(
