AOpen EHW-4048U CD-RW - Page 6

CDR Tests

The AOpen CRW4850 supports 8X, 12X, 16X (CLV), 20X, 24X, 32X and 40X (Z-CLV) writing speeds. When JustSpeed is activated and the inserted media is not supported for writing at the maximum speed, the drive lowers the maximum speed down to 24X. De-activating JustSpeed will enable writing at the maximum speed.

- Recording Tests

The amount of the data we burned was 704MB (80:01:26), for all the drives. The AOpen EHW-4048U finished last with 211secs, while the WAITEC FRISBYII was the fastest drive with 183secs. That is a 28secs difference. The YAMAHA CRW-F1DX came second with 187secs and the PleXWriter PX-W4012U third with 198secs. Below are the best recording time results we had:

- Overburning Tests

The AOpen drive can overburn up to 99 mins with the proper media. It is advised to keep the recording speed down to 8X or 12X with such media.

- CD-Text Results

The drive can read/write CD-Text without any problems.

- CloneCD Writing Tests

The CloneCD software reports that the drive supports the DAO-RAW feature. With the use of proper media, DAO-RAW writing can be performed at 40X. However, in many cases we tried to write above 12X under DAO-RAW mode we always had a coaster. For checking the drive's EFM correction status, we used 3 different game titles with different SafeDisc 2 versions with the latest software patches installed. We used the drive as reader/writer at maximum reading/recording speed. Two discs were burned for each game (Amplify Weak Sectors On/Off). Two discs were burned for each game. One disc burned with PadusDJ and the other with CloneCD (Amplify Weak Sectors On). The results are posted in the table below:

The AOpen EHW-4048U was disappointing when trying to backup protected discs. The AWS (Amplify Weak Sectors) didn't show any improvement and the produced discs did not play in any CD/DVD-ROM drives we tested...
