Well, I ended up taking mine back. If I didn't already have a 40x Plextor I may have kept it.
The Good Stuff:
With OWSC enabled, it burned everything I threw at it. Everything from cheap-ass no-names to TYs. The fastest rated CDrs I have are the Fry's 40x "GQ" brand. Burned them fine at 40x. No errors when checked with Neros' ScanDisc utility in CD Speed. I burned data, audio (mp3 to WAV), images and bootable (made a bunch of slipstreamed Win2000 sp3 CDrs). Used Nero 5.5.9.0. CloneCD 4.0.1.6. Didn't try using the Mt. Ranier or Disc Tatto thingy.
The Funky Stuff
You can't manually set any record speeds between 16x and 44x.
Those are the only choices you have. No 20x, 24x, 32x, 40x. Nothing. If you leave the OWSC enabled, and choose 44x, it will burn the CDr at the fastest speed it considers is safe (that may be 16x, 20x, 24x 32x etc). It burned most of my discs at their rated speeds, at least.
My problem is that I have a lot of discs that are rated (either on the package or on the media) at 12x or 16x that will actually burn at 24x or 32x and give perfect burns (as reported by CD Speed's ScanDisc) in my Plextor 40x or my Lite-on 32x. If I burn these same disks using the Yamaha, they are limited to 16x and 24x, respectively.
If I turn off the OWSC and try to burn I have trouble. Even with the OWSC turned off there is still no option to record at anything but 16x or 44x. If I choose the 44x setting it starts recording at 20x and keeps speeding up (actually forcing 44x) to 24x, 28x, 30x, 32x until I get burn errors and a coaster. So I have all these CDrs that I can't record at the same (safe) speeds as I can with my Plextor or Lite-on.
Yes, DMA is enabled....blah, blah, blah. It does record fine at high speeds, as long as it thinks the discs are good at those speeds, it just doesn't let you choose any in-between speeds to record at.
I talked to Yamaha tech support about this and first the guy told me I had to have the latest version of Nero in order to be able to set my own in-between record speeds. When I told him I WAS using the latest version he then told me I'd have to wait for upgraded firmware or software. Pffft.....
Summary
This burner works fine. If I didn't already have a 40x Plextor that also works fine, maybe I'd keep it.
BUT, the locked-in record speed thing pisses me off. I'd like to be able to record at the speeds I want (and work fine, according to CD Speed tests) .
The blue light is way cool.
The air-bag that the burner's packed in is also pretty neat.
BTW - It's $171 at
