Today I bought a new cd burner and installed it instead of an old 8x4x32 that was working fine until the day it died.
But with this one I have some problems, the kernel recognizes 8 burners instead of one!! :roll:
This is the output of dmesg:

Then it creates 7 "cdrecorder" directories:

And obviouslly I see 8 recorders on mi burning program, it seems I can burn with any of them.
Well, thats all I have to say, any ideas about this?
Thank you.

Oh, well, thank you for the response, but I changed that burner for another brand and now everything is working great. :D

It's a moot point now that you've swapped the drive, but if I had to guess I'd say that you had "Probe all LUNs on each SCSI device" turned on in your kernel, which shouldn't cause any problems but was apparently freaking out the poorly written firmware on the drive.

If this was the case you could have tryed turning off that option and see if it behaved any better. However, since you took the even better approach of returning a badly designed drive for a more reasonable one I guess this will forever remain a mystery ;)

In fact, it's true, I had that option turned on, and if you think it was some kind of bad designed hardware Im glad I chose to buy a better one. :-D
But, as you say, I guess it will remain as a mistery. For the record, it was a MSI 48x24x48.
