Problems with BENQ DW16/40 DVD Burner

dejavu_01 · 01-14-2006, 09:38 PM

Hi

This hardware works like champ in windows, unfortunatly after a migration to Slackware10.2 it fails to work even the basic functions

The first problem I like to mention is it seems that it doesn't want to eject. The result of eject -v gave the following

Code:

arvel@northstar:~$ eject -v
eject: using default device `cdrom'
eject: device name is `cdrom'
eject: expanded name is `/dev/cdrom'
eject: `/dev/cdrom' is a link to `/dev/hdc'
eject: `/dev/hdc' is not mounted
eject: `/dev/hdc' is not a mount point
eject: `/dev/hdc' is a multipartition device
eject: trying to eject `/dev/hdc' using CD-ROM eject command
eject: CD-ROM eject command failed
eject: trying to eject `/dev/hdc' using SCSI commands
eject: SCSI eject failed
eject: trying to eject `/dev/hdc' using floppy eject command
eject: floppy eject command failed
eject: trying to eject `/dev/hdc' using tape offline command
eject: tape offline command failed
eject: unable to eject, last error: Invalid argument
marvel@northstar:~$

Suggestions in this board is to gave chmod 666 /dev/cdrom. I followed the instruction but the error still occurs. No matter as root or normal user. Is this partically burner model BENQ DW16/40 has compatibility probelm with linux?

strangly, when I gave a command dmesg, (while I got a disk stuck up in the drive) yeilded for following result. Is this related to the problem?

Code:

ide: failed opcode was: unknown
hdc: drive not ready for command
hdc: status error: status=0x58 { DriveReady SeekComplete DataRequest }
ide: failed opcode was: unknown
hdc: drive not ready for command
hdc: status error: status=0x58 { DriveReady SeekComplete DataRequest }
ide: failed opcode was: unknown
hdc: drive not ready for command
hdc: status error: status=0x58 { DriveReady SeekComplete DataRequest }
ide: failed opcode was: unknown
hdc: drive not ready for command
hdc: ATAPI reset complete

marvel@northstar:~$

This is on Slackware 10.2 with Kernel 2.6.13

You have something strange going on there in Slack mine works fine in Debian.

Code:

>$ eject -v /dev/hdd
eject: device name is `/dev/hdd'
eject: expanded name is `/dev/hdd'
eject: `/dev/hdd' is not mounted
eject: `/dev/hdd' is not a mount point
eject: `/dev/hdd' is a multipartition device
eject: trying to eject `/dev/hdd' using CD-ROM eject command
eject: CD-ROM eject command succeeded

Now in Debian you have to be in the cdrom group to access is there such a thing in Slack that maybe you have to use as well?

That second part looks like dma errors what does the following commands tell you.

Code:

HappyTux:/home/stephen# hdparm -i /dev/hdd

/dev/hdd:

 Model=BENQ DVD DD DW1640, FwRev=BSLB, SerialNo=9JB5U150C352407627SP
 Config={ Fixed Removeable DTR<=5Mbs DTR>10Mbs nonMagnetic }
 RawCHS=0/0/0, TrkSize=0, SectSize=0, ECCbytes=0
 BuffType=unknown, BuffSize=0kB, MaxMultSect=0
 (maybe): CurCHS=0/0/0, CurSects=0, LBA=yes, LBAsects=0
 IORDY=yes, tPIO={min:120,w/IORDY:120}, tDMA={min:120,rec:120}
 PIO modes:  pio0 pio1 pio2 pio3 pio4
 DMA modes:  mdma0 mdma1 mdma2
 UDMA modes: udma0 udma1 *udma2
 AdvancedPM=no

 * signifies the current active mode

HappyTux:/home/stephen# hdparm  /dev/hdd

/dev/hdd:
 IO_support   =  1 (32-bit)
 unmaskirq    =  1 (on)
 using_dma    =  1 (on)
 keepsettings =  0 (off)
 readonly     =  0 (off)
 readahead    = 256 (on)
 HDIO_GETGEO failed: Invalid argument

Do you get the dma in both after a fresh bootup? Again in Debian I had to install the hdparm program and enable the dma on mine otherwise the burning speed sucked. Another thing you may want to check/consider is if you have the burner on an old cdrom cable you might want to put a newer 80 pin cable in there.

This is what I got...

Code:

root@northstar:/home/marvel# hdparm -i /dev/hdc

/dev/hdc:

 Model=BENQ DVD DD DW1640, FwRev=BSLB, SerialNo=9JB5U150H453719496PP
 Config={ Fixed Removeable DTR<=5Mbs DTR>10Mbs nonMagnetic }
 RawCHS=0/0/0, TrkSize=0, SectSize=0, ECCbytes=0
 BuffType=unknown, BuffSize=0kB, MaxMultSect=0
 (maybe): CurCHS=0/0/0, CurSects=0, LBA=yes, LBAsects=0
 IORDY=yes, tPIO={min:120,w/IORDY:120}, tDMA={min:120,rec:120}
 PIO modes:  pio0 pio1 pio2 pio3 pio4
 DMA modes:  mdma0 mdma1 mdma2
 UDMA modes: udma0 udma1 *udma2
 AdvancedPM=no

 * signifies the current active mode

root@northstar:/home/marvel# hdparm /dev/hdc

/dev/hdc:
 IO_support   =  0 (default 16-bit)
 unmaskirq    =  0 (off)
 using_dma    =  0 (off)
 keepsettings =  0 (off)
 readonly     =  0 (off)
 readahead    = 256 (on)
 HDIO_GETGEO failed: Invalid argument

Your dma is not being set use hdparm -c1 -u1 -d1 /dev/hdc that will give you the same settings I use you should put this command in a startup script or if the Slack setup is like Debian it is set in a config file /etc/hdparm.conf.

dejavu_01 · 01-15-2006, 01:26 AM

thanks, I've given the suggested command hdparm -c1 -u1 -d1 /dev/hdc and now I got the same resualt as you.

Code:

root@northstar:/home/marvel# hdparm -c1 -u1 -d1 /dev/hdc

/dev/hdc:
 setting 32-bit IO_support flag to 1
 setting unmaskirq to 1 (on)
 setting using_dma to 1 (on)
 HDIO_SET_DMA failed: Operation not permitted
 IO_support   =  1 (32-bit)
 unmaskirq    =  1 (on)
 using_dma    =  0 (off)
root@northstar:/home/marvel#

But.... it still doesn't want to eject the cdrom

Code:

root@northstar:/home/marvel# eject -v /dev/hdc
eject: device name is `/dev/hdc'
eject: expanded name is `/dev/hdc'
eject: `/dev/hdc' is not mounted
eject: `/dev/hdc' is not a mount point
eject: `/dev/hdc' is a multipartition device
eject: trying to eject `/dev/hdc' using CD-ROM eject command
eject: CD-ROM eject command failed
eject: trying to eject `/dev/hdc' using SCSI commands
eject: SCSI eject failed
eject: trying to eject `/dev/hdc' using floppy eject command
eject: floppy eject command failed
eject: trying to eject `/dev/hdc' using tape offline command
eject: tape offline command failed
eject: unable to eject, last error: Invalid argument
root@northstar:/home/marvel#

problem solved!!!! :-)

Cause of probelm : User eror

Details: Since I made the jugment based on a set of funky CDroms a friend of mine burned for me on his Windows machine - possibly a multi session disk or some thing that linux might not like. I can sucessfully burned CD in linux with k3b at high speed. Then be able to mount it, umount and eject all very smoothly now. This is a user fault. Thanks so much

dejavu_01 · 01-21-2006, 03:19 AM

Well, I hate to say this, but actually, the problem is still there. I was tricked into beleaving that the problem lies in the disk (hence previous post), but the drive is still not yet functional. This time I can't read from a newly bought Quake4 DVD :-(

HappyTux, what kernel are you using? 2.4 or 2.6. I've been told that 2.6's DVD burner compatibility is broken.... ? I'm now on 2.6.13 going to try downgrade to 2.4 this weekend.

I'm using 2.6.12 with the Con Kolivas kernel patch 2.6.12-ck6 the burning or anything else for that matter works fine here I burn dvd on a regular basis and use the IDE not IDE-SCSI for the access so my drive shows up as /dev/hd? not a /dev/sd?.
