5. Each drive is held in place by a tray with two screws.
   
   • Gently press down and hold on the plastic latch with your index finger.
     This will unlatch from the metal frame of the drive.
   • Grab the plastic tray with fingertips and pull gently.
     
   • The tray and drive should easily lift upwards or slide out.
   • Keep track of the drive order/position.
     Each drive will need to be put into the new enclosure in the same order/position.
   • DO NOT remove the drive trays from the drives.

   The tray should slide in with ease. Do NOT force it. The side of the drive with the SATA and power connector must point down in the unit. The side of the drive with the small serial number label must face up. The latch must be on the side of the tray that is closest to the rear. The drive is inserted once the plastic latch connects or latches into the metal chassis of the unit.



5. Put the top cover back on.
   The end with the curved hinges goes in first.
   Press down on the other side of the lid until it is flush with the top.
