Protected Disc Tests
- Reading Tests
To create the image of the various protected titles to the hard disk, we used Alcohol 120% software and the appropriate settings, according to the protection type of the inserted discs. Below you can see the duration of each process as well as the transfer rate in each case.

The LG drive performed well with two second places and a first.
- Writing Tests
The drive supports the DAO-RAW writing mode. For checking the drive's EFM correction status, we used 5 different game titles with different SafeDisc 2 versions having the latest software patches installed. After copying the images of the various titles onto the hard disk, we burned them (maximum speed) with Alcohol 120% v1.9.2.1705. Two different discs were created for each title; one with the "Bypass EFM error" enabled and one more with the function disabled.
- Fifa 2004 - Safe Disc v3.1x
- The Sims Superstar - Safe Disc v2.9x
- The Sims Unleashed - Safe Disc v2.8x
- Serious Sam Second Encounter - Safe Disc v2.51.021
- Max Payne - Safe Disc v2.51.020
The table below shows the results of the attempted backups and whether they worked (game installed / played normally), or not.

The LG GSA-4120B can backup accurately only up to SD v2.8, while it fails to backup SD2.9 and the newest 3.1 without EFM correction on.
