How to open external drive case?

The fan is failing in my Plextor PX-712UF external drive and I can’t figure out how to open the case? Any suggestions?

Thanks,
Bill

It’s pretty easy to open the case. Turn the drive off first, then use the emergency eject tool or a paper clip to open the drive tray via the emergency eject hole. Remove the bezel from the tray. Unscrew the single screw on the back of the enclosure and then slide the top half of the case back (away from the front of the drive). After that you will see the internal drive in another enclosure, but then it’s just a matter of removing all of the screws.

Oops. I had removed the only external screw and still couldn’t get it apart. So I banged on the back edge and the top cover slid back and lifted off. Hopefully this will help someone else.

Thanks “Two Degrees”, your approach is better than mine. --Bill
