I just took apart my RX02 to clean them since they were getting flakey. On a previous drive I just went to a craft store and bought the closest material I could find, cut it to a small dot to fit in the cup. Put a drop of glue in the cup and push the material in. To get the drive out for access. 1) Remove from outer shell if you have the desktop unit. The top cover comes off with obvious screws then ones along the side free the internal unit. 2) Disconnect the cables to the controller board and motor power connector on the back of the drive hidden by the air baffle. 3) Remove drive from rest of assembly. 2 screws through the air baffle at the back and 4 from the top down. If you tilt the upper board up on the hinge they are accesible through holes in the lower PCB. That should free the drive. You can then lift up the little presure arm to easly get at the pad. I don't have any real RX01's so they might be slightly different for disassembly.
