Page 2 - Certified Speed Tests

CD #1 Burned @24x:

As you can see, all three tests reported significant errors. Nero CD Speed and CD doctor both report thousands of C2 errors! What is even more notable than that, is the fact that the CD-R's file system is unreadable!! if you look at CD Speeds's Scan Disc test (upper right), You will notice that it was unable to test any of the files on the disc for readability, because it couldn't even FIND the files. This is most likely because of the high amount of errors at the beginning of the Disc where the table of contents is stored. Most likely the table of contents is corrupted to the point of making this CD-R completely unreadable to windows. Data would be VERY difficult to recover from this disc... and this was burned at the CERTIFIED speed.

CD #2 Burned @24x:

The first thing I should mention about this test, is that Nero reported this CD as having FAILED during the burn process! However, this CD-R actually performs a little better then the first test CD-R, which didn't fail during the burn. We can see in Nero ScanDisc, that all but 1 out of 69 files were readable... however, we can also see the LARGE amount of reported unreadable blocks! CD Doctor also reports a very high amount of C1 and C2 errors, and once again, I am glad I don't have anything important on this CD-R!!

CD #3 Burned @24x:

There Isn't really much to say that is different about this test then the last 2. Only the CD-R did not fail during the burn process, and this time 7 out of 69 files were not able to be read completely! We are still seeing thousands of reported C1 and C2 errors! Now let's see what happens when we push this CD-R to FASTER speeds.
