KS04-KS09 and back

Successfully got to KS04 on my Sony D26. 4 minute Full CD burns with verify. When I upgraded to KS09 last month, burn time jumped to more than 15 minutes. Put back to KS04 this morning, and burns now are 4 minutes again.
I guess I should stay at KS04.

The old firmware, when reviewed, was cited for problems with burning CDS. I have read that the updated firmware had solved the CD quality issue. It is possible it is slowing down the MAX burn speed in favor of a quality burn. Just a thought.

I don’t understand what you mean by “old” firmware. The slower KS09 was the latest release.

#4

KS04 is older and had problems with CDs. KS09 is newer, and is reported to have resolved these problems. This is the review that reported the problems; another poster here stated that KS09 had fixed this.

My experience is exactly the opposite.

Just stick to the firmware best to you, newer is not always better.

@ekaxel
Try and do a KProbe quality scan and see which firmware gives better burn, maybe faster speed will result in quality drops (Unless you care about speed more) :slight_smile:

KS04 will give you C2 errors on CD-Rs burned at 48x, which are very bad :(.

Upgrade to KS09 again (make sure you use crossflashed firmware (see my signature)) and check that DMA is enabled after the flash ;).

Reflashed to KS09. Don’t know what I did different, but much better. About 5 min for a 675mb data CD with verification.
Thank you.

I routinely see different speeds on CMC discs in the same stack. My Plextor Premium will adjust the speed to maximize quality and I get a range of 16X to 32X on the same discs. Possibly you have something similar going on. Anyway, glad you are content. No amount of speed is worth C2 errors.
