while the Seagate 10Tb IronWolf ST10000VN0004 is shown as compatible in the Netgear list, the drive lacks the middle screw hole and therefore will not accept the drive carriage without cutting off the plastic carriage pin, thereby removing one of its alignment guides. I note that the photos of this and other Seagate drives on Amazon do not show the side where the holes are, whereas the W/D drive photos do. I'd really like to see "physical compatibility" addressed on the list as well as electronic compatibility, but contacting Netgear re something like this is not easy.

You can secure it well enough using two screws to mount via the holes in the bottom, with or without the (modified) plastic insert. I frankly don't know why Netgear went to the plastic insert. It's not like people swap out their drives on a regular basis.

FWIW, Netgear has already addressed it. Newer trays have been modified.
As @Sandshark says, you remove the plastic insert and use the screws that came with your NAS to attach the disks to the bottom of the tray.
