Improvements of the Liteon 166S

I found this at CDRlabs.com. Thanks to Ian.

Unique Features of LTD166S

  1. User protection against fragment of crashing disc :
  • New top cover with folding edge
  1. Acoustic noise improvement
  • No damper screw hole on tray
  • Stream-line design of chassis loader to reduce noise induced by air flow in the drive
  • New bezel and top cover design
  1. IDE cable Short prevention
  • Isolate IDE connector and bottom cover to prevent IDE cable short caused by direct contact with bottom cover
  1. Disc scratch free design
  • New tray design with contacting slope to prevent disc scratched by tray in OD area.

Essentially, it protects you from exploding discs (didn’t Lite-On say they weren’t really concerned about this?) and its quieter.
