Write Performance, Part III: Media Compatibility, Continued

The following is a summary of the CD-RW results.

Tested Media
CDRW		 Size Certified Speed Write Speed Strategy Manufacturer Good Sectors Unreadable Sectors Write Time
Fuji 650 MB 10X 12X Phase change Disc ID not allowed 99,89% 0,11% 6:56
10x 99,89% 0,11% 8:09
LiteOn 650 MB 12X 12x Phase change NAN-YA Plastics Corp. - - -
12x 10x 99,89% 0,11% 8:07
Yamaha 650 MB 24X 24x Phase change Mitsubishi Chemicals Corp. 99,89% 0,11% 3:48
10x 10x 99,89% 0,11% 8:09

The LiteOn medium is indeed specified as 12x. But Nero won't permit any write speed over 10x for this medium. At first glance, the burner does not seem to be able to write to any medium without making errors. However, comparing the surface scans of the various media shows that the last sectors are always unreadable on each of the media.

A surface scan with different drives delivers exactly the same results. Even CDRs written in TAO mode show this failing. So, we changed the method of writing from TAO to DAO, and carried out all the measurements again.

Tested Media
CDRW		 Size Certified Speed Write Speed Strategy Manufacturer Good Sectors Write Time
Fuji 650 MB 10X 12X Phase change Disc ID not allowed 100,00% 7:24
10x 100,00% 8:03

Yamaha 650 MB 24X Phase change Mitsubishi Chemicals Corp. 100,00% 4:46

This time, everything ran like clockwork.

  • I am glad i found this article/review. I have a crw-f1ux minus the needed software. While I am not so interested in discT@2, I would like to use Advanced Audio Master Quality Recording, to create audio cds. Do you know where one can get said software? Yamaha does not have it, nor does Nero answer their phones during stated business hours. I currently use Easy CD creator, but I suspect I need the FULL version of Nero that came with this 2002 unit. While I wait for Nero's reply, would you happen to know? Thank you in advance.
