 |
|
Hi,
I cannot use my cdwriter because cdrecord does not recognize it. Here is the output from cdrecord:
| Code: |
tux root # cdrecord dev=ATAPI:0,0,0 -checkdrive
Cdrecord-Clone 2.01a37 (i686-pc-linux-gnu) Copyright (C) 1995-2004 Jörg Schilling

cdrecord: Sorry, no CD/DVD-Recorder or unsupported CD/DVD-Recorder found on this target.

I have the modules ide_cd and cdrom loaded, and my kernel recognizes the drive correctly:
| Code: |
hdc: SONY CD-RW CRX320E, ATAPI CD/DVD-ROM drive
|
So what can I do?
Thanks,
Kalle |

there are plenty threads about this. downgrade your kernel, or patch it at your own risk:
| Code: |
--- linux-2.6.8/drivers/block/scsi_ioctl.c~2004-08-16 14:16:57.000000000 +0200
+++ linux-2.6.8/drivers/block/scsi_ioctl.c2004-08-16 14:36:22.562908552 +0200

Thanks for the suggestions. The patching didn't help. I think the patch is actually included in the 2.6.8-gentoo-r3 sources. I also tried nitro sources, but I still get (running as root):
cdrecord: Sorry, no CD/DVD-Recorder or unsupported CD/DVD-Recorder found on this target.
The nitro sources seem to be a step forward because now my dmesg contains:
hdc: ATAPI 12X DVD-ROM CD-R/RW drive, 2048kB Cache, UDMA(33)
Well, I'll try to downgrade the kernel, or perhaps play around with scsi emulation in the new kernel.

the patch works for me using 2.6.8.1 from kernel.org.
however, maybe you run a recend version of cdrecord - dunno what the latest in portage is. Joerg Schilling, the cdrecord author, is an a WarTrip currently against SuSE and whomever, he is even in Alan Coxs killfile <g>. i stopped reading the kernel newsgroup infact of this.
maybe you should use an older version of cdrecord? i am using:

//edit: i just realize 28a is not in portage anymore  |
