ReadyNV: Can´t get out the Tray...

I have the exact same problem and it's really frustrating. I managed to eject the drives using method 'B' but every button is totally frozen. This only occurs on the 3 drives installed, the spare was difficult to open but it eventually did normally with a lot of pressure on the button. I removed each drive and took off the plastic latch mechanism and they are all still permanently stuck. Toggling the lock on the back of the latch does nothing.

I have the NV and paid a lot of money for it. It's frustrating that I can't remove the drives and it's obvious that the release buttons freeze after time, which in my mind means they are defective. Having to stick something into the openings to get the drives out is lame. Is there any possibility of replacing the 4 defective latch mechanisms? I could also repair them with instructions, but it's not obvious how to disassemble them and/or lubricate them.

Thanks,

Jeff
