DVD Writer / Playing DVD Problems
I have a Pioneer A05 DVD Writer:
[root@siren root]# dmesg | grep CD hdc: PIONEER DVD-RW DVR-105, ATAPI CD/DVD-ROM drive hdc: ATAPI 63X DVD-ROM DVD-R CD-R/RW drive, 2000kB Cache, UDMA(33) Uniform CD-ROM driver Revision: 3.12 The following configuration works great for playing DVD. (So they are not choppy) /etc/modules.conf: alias parport_lowlevel parport_pc alias eth0 3c59x alias eth1 3c59x alias scsi_hostadapter aic7xxx alias sound-slot-0 emu10k1 post-install sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -L >/dev/null 2>&1 || : pre-remove sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -S >/dev/null 2>&1 || : alias usb-controller usb-uhci alias char-major-195 NVdriver options ide-cd dma=1 probeall aic7xxx ide-scsi alias scis_hostadapter1 ide-scsi #options ide-cd ignore=hdc But cdrecord and dvdrecord can't find the drive with -scanbus. Thus I can't burn CD/DVDs. If I uncomment the "options ide-cd ignore=hdc" line cdrecord and dvdrecord can find the drive and I can burn CD/DVDs but.... playing DVD's is very choppy. (because DMA is not active) Any ideas how I can have both configurations working? Thanks. |
you could try to run
Code:
/usr/sbin/hdparm -d 1 -u 1 /dev/hdc in your distro of choice :}) Quote:

[root@siren root]# hdparm -d 1 -u 1 /dev/hdc
/dev/hdc: setting unmaskirq to 1 (on) setting using_dma to 1 (on) unmaskirq = 1 (on) using_dma = 1 (on) [root@siren root]# cdrecord -scanbus Cdrecord 2.01a01 (i686-pc-linux-gnu) Copyright (C) 1995-2002 Jrg Schilling cdrecord: No such file or directory. Cannot open '/dev/pg*'. Cannot open SCSI driver. cdrecord: For possible targets try 'cdrecord -scanbus'. Make sure you are root. cdrecord: For possible transport specifiers try 'cdrecord dev=help'. If I uncomment the line hdparm doesn't find /dev/hdc... of course. |
DVD Writer problem fixed
For anyone who has a similar problem.
I took out the "options ide-cd dma=1" line and everything is working great now. |
