WARNING: Hardware Compatibility List has non-compatible models on it

Last night I looked up my ReadyNAS 314 on the Hardware compatibility list and found a new drive to purchase and install.  However Netgear in creating this list obviously does not physically test the drives in an actual NAS.  At least two of the 6T drives listed DO NOT have compatible mounting holes for the plastic quick mount feature, also the bottom mounting holes were you could attach screws only aling with two holes.

Here is a screen capture from the Netgear provided instructions.  It accurately shows the black plastic bracket and tray. This matches my current drive that I was replacing.

Here is a clip of the drive listed on the compatibility list, 6th one down.

 And here is a picture of the Physical Drive.

As you can see, unlike the older drive that I have, this "Compatiable" drive only has four mounting holes, one at the front and back of each side, rather than six--the middle one.  The plastic mount sleeve requires the middle and back holes.

So this drive does not PHYSICALLY fit the device.

My question is how do they know it is compatible?  They obviously did not physically test it or they would have discovered the problem.

Yes there are holes ont he bottom, but only two of the four line-up.  I am not an engineer, but I belive you need three points of contact to secure the drive from being able to twist or pivot.
