I have a SATA Plextor PX712SA DVDRW drive installed on the second SATA channel of my ECS 755-A2 Board.
My SATA HDD is on the first channel and it works fine. It took a while to get the boot order working, but that is another issue.
The DVDRW works under Win2000 and is recognized as a SCSI device.
Even though I have the sata_sis module loaded and working, The DVDRW is not recognized at all and does not show up under /dev or /proc.
Is there a common Major and minor I can use in mknod to make the drive visible? Is there a newer way of accessing a CD/DVD device on a SATA channel? I love the versatility of this drive, but I can't use it at all under Linux. I don't want to give up and buy the IDE/ATA version of the same drive.
Any help or suggestions would be greatly appreciated.
I'm running the 2.6.10-rc2-bk6 kernel and ahci drivers on a Dell Precision Workstation 370 that uses the Intel ICH6R chipset and haven't been able to get my PX712SA to work either. Works under WinXP in full AHCI SATA mode, but no devices nodes created under linux. I'm starting to suspect that as Plextor and MSI are the only manufacturers to release SATA DVDRW drives that the support just hasn't been coded into the kernel yet.
Ha! You big cheater, where's the fun in that? Anyways, I might just try email the kernel's SATA maintainer and ask if I'm even supposed to have support for that burner.
I'm not sure how much I can help with this, but some information is better than no information.
You didn't say anything about dmesg, or the /etc/fstab file. If these are working fine, and you have a mount point and filesystem to go with, then it's just a matter of getting the software you want to use to recognize the dvdrw. Unfortunately I have had some problems with my own cdrw, and getting xcdroast to recognize the drive.
If it's not too much trouble could you post part of dmesg showing this device. Maybe we could go somewhere with that.
When you say that it doesn't work at all, you mean that Linux does not mount anything in it, even a data cd or another linux cdrom, or something.
<You didn't say anything about dmesg, or the /etc/fstab file.>
That's just the issue here. The drive does not even show up on the ATA subsystem in dmesg. The bus is available and my SATA HDD is seen as sda with SCSI emulation on the IDE2 (third IDE chnnel after IDE0 and IDE1), but nothing on the second SATA channel (IDE3).
Hey jourbans- I bought a LaCie USB2 16X DVDRW Double Layer burner today and it works fine under Linux and Wind0z3. Cost a lot less than the Plextor I really wanted...
Still waiting for this thing to be recognized.................
Using the AHCI drivers, everything *should* be getting picked up by the SCSI subsystem, but it's not there. Dmesg output shows the drive as being intially detected, but then no device nodes are created (using either devfs or udev, I tried both). After boot, the drive is nowhere to be seen in the SCSI tree (using lshw), as opposed to my HD which show up with no problem.
I can get it to show up if I switch the BIOS over to IDE/ATAPI emulation, and config my kernel for that, but why would I do that? I want *pure* SATA, if I wanted IDE I'd have bought IDE.
Here's my relevant dmesg output:

The symptoms reported in that post are nearly identical to mine. From what Google's language tools and my shitty high school German can tell me, it looks like the poster got it working with IDE emulation mode, which, again, I don't want to do.
ECS 755-A2 mobo- 754-pin A64/3200+
1GB 400mhz DDRAM
Sis 755/694 chipset 1600mhz HT bus
two SATA ports, two IDE channels, lotsa USB ports

usual PCI/AGP/AMR/serial/lpt ports...
I don't think from what has been said here that this is unique to the chipset involved.
Looks like an issue with recognizing the device with the libata/sis_SATA driver base.
Gonna hafta wait until there is more work done on the SATA system in Linux.
Here's my dmesg using 2.6.12-rc3 with ATA_ENABLE_ATAPI enabled in libata.h. With that enabled, I can read and mount media to my filesystem, watch DVD's, and rip CD's with cdparanoia. I can't burn to CD or DVD media though. Looks like packet writing is still rough.

Which kernel ebuild are you using? I'm using the ~x86 tree and my gentoo-sources are still at 2.6.11-r9. Did it work with an earlier kernel? Could you mail me your .config to [spam6461 at email dot si] so i can see if there are any significant differences in our config? I'd really appreciate it. If I find any i'll post them.
Not using a kernel ebuild, just downloading the source and latest patch from kernel.org. Kernel building the manual way, eh? I'll send along my .config for ya.
Not a fan of eyecandy myself, but all my other boxes use the latest gentoo-sources. Just using the (near) latest version of the kernel because of this SATA burner. Once (if ever) the burner support gets stabilized, I'll start using gentoo-sources on this computer.
