Philips JackRabbit4 DVD+RW recorder - Page 6

- Reading Tests

To create an image of the various protected titles onto a hard disk, we used CloneCD v.v4.3.1.9 software and the appropriate settings, depending on the protection type of the inserted discs. Below are summarized the capabilities of Philips JR4DVDRW drive, according to CloneCD software.

The game titles we used for each protection scheme are given in the table below:

PSX Pressed Media

SafeDisc v.2

SecuROM v.2

By taking a look at the three previous graphs we can see that no matter what the game type was, Philips performed very well, while also producing much faster tranfer rates than the Pioneer drive.

- Writing Tests

The Philips JR4DVDRW supports the DAO-RAW writing mode. For checking the drive's EFM correction status, we used 2 different game titles with different SafeDisc 2 versions with the latest software patches installed. After making the images of the various titles to the hard disk, we burned them (maximum speed) with CloneCD. Two different discs were created for each title; one with the "Amplify Weak Sectors" enabled and one more with the function disabled.

The table below shows the results of the attempted backups and whether they ran (game installed / played normally), or not.

As can easily be seen from the table above, the Philips drive could only create working backups of v2.51 game protection scheme.
