I installed K3b, 0.10.1, among with other stuff such as DVD+RW tools. I also installed my new dvd-writer that can handle both -R/W & +R/W discs.
But when trying to write a dvd-rw, K3b returns the following error:

I use scsi-emulation for all my optical drives.
But why can't it change speed? Faulty writer or is there a setting or something I should change somewhere?
Cheers!

Wouldn't be a Sony would it? That's exactly the problem (among others) I was having with a new Sony 510A. I found on the Sony website that even when by itself the Sony will not work right if pinned "Cable Select" but has to be pinned "Master" when alone. I changed the pinning and now it's great other than the fact that it sounds like a thrashing machine while burnibg a CD.

Nah, it's a NEC ND-1300A. And I've pinned it as master, for some reason I never use cable select. But, master, sec. ide-channel and a slave NEC CD-ROM (old).
But perhaps I should try having it alone on that ide-channel?
