Thanks to hard work from the folks at CDRLabs, particularly “cfitz” and “Ian”, there is now an English translation of the new media testing program, CD Doctor. This program appears to be based on the Sanyo internal testing program, and measures C1-C2 errors on Sanyo and LiteOn drives. It runs in Windows, which makes it a little easier than WSES. Results of disc scans in both WSES and CD-Doctor appear to be very similar in terms of the errors reported.
Here is a list of drives that are known to work with this program:
Lite-On LTR-32123S (read error reported when using Nero ASPI)
Lite-On LTR-40125S (4KUS CDR-5W32)
Lite-On LTR-48125W (4KUS CDR-5W32)
Lite-On LTR-52246S (CDR-6S48)
Please read the entire thread at CDRLabs to learn more about this program and download it (free),
Please note that you will need to have ASPI installed for this program to work, I used 4.60 in Win2000. Also note that the error display has a logarithmic scale which can make different results appear similar at first glance.
