Philips Mt Rainier Rewritable Validation Suite - Page 5

- Test Methodology

For testing the Mt. Rainier standard implementation from each manufacturer, we used the EasyWrite Test Suite and test discs. After registering the software, we tested all current drives that support, or at least claim to, the Mt. Rainier format. Our purpose was to check which drives have better Mt. Rainier implementation and which one can pass the "EasyWrite" standard. All drive were flashed with their latest available firmware:

Tested Drives Firmware Revision

ASUS CRW4816A v1.00
LiteOn LTR-40125S vZS.0J
LiteOn LTR-48125W vVS.06
MITSUMI CR-480ATE v1.0E

TEAC CD-W540E v1.0C
YAMAHA CRW3200E v1.0d

After loading the MRW Part A v1.6 script in the Philips Suite software, we select the tested drive. We press the "Start", and the software prompts for entering the name that will save the test report. The drive starts the testing procedure and shortly asks to enter a blank disc.

The testing continues and the available log file is updated in real time, showing the command set executed and the test result for each test. The log file indicates which commands are PASSED or FAILLED by the drive. In some cases a failure in a specific command does not affect the test procedure. If the failure is severe, then a fatal error occurs and the test is terminated.

The Heavy and Light R&R scripts run in a similar way, producing successful or failure results.

The three scripts (MRW Part A, Light/Heavy RnR) are executed with blank and only the Light/Heavy RnR scripts with defected media.
