SATA Optical Drive (DVD Burner) not recognized

squisher · 04-04-2005, 10:40 AM

Hi,
I have a SATA dvd burner connected to an nforce4 motherboard (nv_raid driver). The drive works fine under Windows but not at all under linux.
In fact, dmesg only recognizes it as ata4, but does not assign it to any device.
I've tried the libata patches for 2.6.11, I've tried 2.6.12-rc1 but no change - the drive does not show up.

Does anyone know how I can get this to work? My computer is somewhat crippled without an optical drive, I'm eager to get this to work :-)...

Thanks in advance for any hints.

Try force loading ata_piix at the start (might put it in your initrd). See if that helps.

Oops.. that might only help on non-nForce. So probably won't work in your case.

Yes, I think that's the case - piix is for the Intel chipsets, IMHO.
SATA itself runs perfectly fine - I also have a SATA hdd - just the DVD does not work.
Thanks for the try though

Try forcing the drive to scsi. Works for me.

Hmm, and how do you do that?

I'm just curious, because I can close my own issue now:
With 2.6.12-rc1 it works if you #define ATAPI in $KERNEL_SRC/include/linux/libata.h , which was already defined in 2.6.11 with libata patch, that is why I had not checked at first. Now I have access to the DVD drive, finally!
