ReadyNV: Can´t get out the Tray...

I had the same problem with a drive try since I bought mine. I fixed it permanently using the following method (this may void your warrenty). It's a bit long, but I tried to be descriptive at possible.

You will need:
#2 philips screwdriver (+)
1.4mm screwdriver (-)
small file (very fine grain), or sand paper (400+ grit)
touch of lubrication oil (plastic safe)
touch of locktight for plastics (optional)
Towels, water, and a touch of patience

1) shutdown NAS, pull sticky tray using the method above.

2) remove the drive, put it in a ASB (anti-static bag)

3) There are 2 screws inside the tray at the front, remove these with a #2 philips screwdriver. Be careful, it's only screwed into plastic - stripping the plastic will make getting it back together much harder (i.e. filler and drilling) let the screwdriver do the work. You might need to torque it a bit to start.

4) With a slight tug, the front piece should come out, on the back there is a small spring. I removed this by using a 1.4mm screwdriver, putting it into the spring (not the looped end) and gently pulling back and up to pop the spring off the latch without damaging it. Leave the spring attached at the other end.

5) Remove the front button panel. You will notice (on the reverse side of the button) that there are two hooks holding the front panel button onto the front plate (ignore the hooks near the spring you just detached for now); these hooks are about 1/4" long Using the 1.4mm screwdriver, gently slide the blade into the edge, and gently pry so the latch moves towards the center of the panel. Do NOT twise the blade, just use the side of the panel as leverage. I used another small screwdriver (paperclip will do) to push down on the front panel button piece (through the hole) at the same time. This allowed the hook to slide down and remained unlatched while I worked on the other side. Repeat for the otherside and gently push out with the screwdriver. This should come out with the following parts:
- front button panel
- front button
- front button latch piece (a small angled plastic piece on the back of the button)
- 2x springs

6) Remove the latch from the panel. The latch is the piece which you detached the first spring from. This should be easy now that you have already removed the front panel button. Use the same process (gentle pressure, and pushing) to pop out the piece. There are 4 latches on this piece. You should have:
- latch
- latch spring

7) How it works: There is a angled piece (front button latch piece) that sets against a post behind the button, which is free floating. The angle faces out, away from the center of the button. The latch piece fits snugly against this, with a corresponding angled piece to rub against the front button latch piece. This also lays flat against the back of the button. In an optimal situation, this latch should move freely with little resistance; with a total travel of 1/16" or so of movement. In my case, this piece was very tight and could not move properly.

8 ) First, use the lubrication oil (very small amount) and lube the latch piece and the area where that lands on the back of the button. Try moving the latch again. If it does not make the movement easy, go to step 8A, otherwise move to step 9.

8A) Since the oil failed, remove the front panel latch piece from the back of the button, and get your small file / sandpaper. Carefully sand the sides of the small end of the latch piece (the sides that touch the edge of the front panel latch piece, not the side that touches the back of the front button. Also carefully sand the inside edges of the stabilizing brackets on either side of the back of the button (where the small end of the latch piece touches it). You should remove the front button latch piece before doing so (and replace it when you are done). Make sure to continually refit the pieces and check for smoothness; you probably won't have to do all of this to make it work. It shouldn't take much filing to get the pieces to fit smoothly. Once completed, blow out bits and use towels / water to clean the plastic bits, and put a touch more oil in for good luck.

9) Re-assemble the latch and the front panel. Take the latch and snap it in to the front panel. You shouldn't be able get this this back in wrong. The small end of the latch should be near where the button will be, with the angled piece facing towards the front. Using the 1.4mm screwdriver, re-mount the spring for the latch.

10) Re-assemble the front button panel. Place the front panel piece face down on the table. There is a straight end and a slightly angled end. Take your button, and place it into the back of the front button panel, so that the angled front panel button latch piece is facing the angled edge of the front panel (the angled latch piece on the back of the button should be facing the angled piece on the front panel. Place the springs on the spring mounts for the front panel. Carefully pickup the front panel, keeping it upside down, and put it into the front piece. The angled piece of the front panel should be placed against the raised section of the front piece. Carefully push the pieces together, making sure that you don't dislodge the front panel latch piece; also make sure the springs get into there respective spring mounts in the front piece.

11) Test it! press the button, you should see the latch move; now with little effort. close the handle and try it again. If it doesn't work properly, you need to make more adjustments and test more carefully before putting it back together.

12) Re-assemble hard-drive carriage. Place the metal disk tray on the table, with the open side facing up, and the small metal side facing left. Place the front panel on the table with the button away from you. Push the two pieces together, and you should see two tabs go into the hard-drive tray. Use the #2 philips screwdriver and screw the tray it. Just make it tight, too much pressure will strip the plastic. You can use locktight to make sure the front panel mounting screws don't come out; you'll be fine without it though.

13) All done! Test fit the fixed tray in your NAS. Should work great!
