Slapped a (very) old Yamaha 16x10x40 CD-RW drive into a friends equaly old PC, since he didn't have a cd burner in it. I did a test burn on it using Memorex 52x CD-R's (a Ritek). Due to the slowness of his computer, I burned the disc at 8x. This is what the quality scan (using Nero CD Speed) came back as:

General Information
Drive: JLMS XJ-HD166S
Firmware: DS1C
Disc: Audio CD
Selected speed: Maximum
C1 errors
Maximum: 3
Average: 0.00
Total: 13
C2 errors
Maximum: 0
Average: 0.00
Total: 0
Jitter: n/a
Scanning statistics
Number of samples: 12468
Average scanning interval: 0.21 sec
Glitches removed: 0


Now granted it was only about 42 minutes long, but still: C1 Average=0.00

If that's accurate (and I know the results from a DVD-ROM aren't 100% accurate), then I may just steal this drive and use it for archiving my important stuff!

Wonder what it could do with TY's...

Edit: Orginaly posted that the disc was a CMC, since it was a Memorex. However, it's a Ritek - the first Memorex's I've seen that were Ritek. Guess I should start buying Memorex again, since Maxell's CD-Rs aren't Riteks anymore....

My daughter has my Yamaha 3200 something CD-RW in her PC now. Those Yamahas were great burners. Second only to Plextor, and not by much, if at all.

Use a Lite-On CDRW drive for scanning for C1/C2 errors. That 166S DVDROM will not give you accurate results.

The yamaha isn't supported by the software when it comes to error measurements that's while you get 0 back.
I don't know if the Yamaha can actually read C1. C2 it can however it does it in a way no programm supports of today at least that was what I heard years ago when the drive was released.

Cheapest way to get a drive for testing will probally be picking up a Lite On.
Like the people here allready suggested.

That scan was done on the 166 DVD drive; it's the only thing I have to scan with at the moment. Still waiting for my BenQ 1620...

Like Bhairav said, LiteOn DVD drives are not useful for scanning CDs. They report C1/C2 in a different way from a CD burner (Karr Wang said "cooked" as opposed to "raw").
