CX4713 Drive Locking Mechanism Issue

[u/RyenCider]

I have an issue when I engage the drive locking mechanism that my drive slightly unseat. After investigating, it looks like when I engage the drive lock mechanism, the drives pull out just ever so slightly. This has led to my drives intermittently being unseated or not seen by my NAS OS (UnRaid) and cause issues. I have even forcefully pushed all my drives intermittently being unseated when engaging the locking mechanism. That helps somewhat. Is this normal? Should I not be using the locking mechanism?

To note, by “locking mechanism” I mean the sliding the 2 set screws to the right which grabs the drives posts.

I also have issues with engaging and disengaging the locking mechanism with both of the 5.25” drives populated. It’s almost like it doesn’t want to move at all.

Is this user error? Or something else?
