- Test Analysis

The test results showed that only Philips RWDVD1610 managed to fully pass the "EasyWrite" standard. The drive didn't have any problems with the MRW Part A and Light/Heavy RnR testing.

TEAC CD-W540E managed to finish, without errors, the Heavy & Light RnR scripts but it doesn't support the "Early Eject" and "Read/Write in Ice" commands, while "Test GAA Addressing" couldn't be tested.

Mitsumi was among the first manufacturers that heavily advertised the CR-480A TE and CR-485C TE as the only EasyWrite compliant drives. However, the test showed the opposite behavior. Both drives passed the MRW Part A script (basic commands) but not the Light & Heavy RnR scripts. The drives locked after the end of each test, and a reboot was necessary to manually eject the test media. This was noticed with both normal and defect media.

LiteOn LTR-40125S, LTR-48125W and TDK CyClone 401248B passed the MRW Part A script, however they failed to complete the Heavy RnR and Light RnR scripts.

ASUS CRW4816A had probably the worst Mt. Rainier implementation from all tested drives. With firmware v1.00, it only executed the first 3 commands, and then locked. Reboot was necessary to eject the used test disc. This behavior was noticed also when we used either InCD or Write CD-RW! Software in our Mt Rainier application tests.

Lastly, the Yamaha CRW3200E didn't accept the script commands, failing to complete any test. Possibly the drive does not follow the MMC standard for the Mt. Rainier format, the way it should be…
