[DVD Writer] doesn't exist can't mount !!!

Hi All

I have an ATAPI CD/DVD Writer "PIONEER DVD-RW DVR-106D" and my system finds it, but actually thats all!!!
When I try to mount it with "mount /dev/hdb /media/cdrecorder" it fails, asking me the type and format of the media

Code: Select all

mount: block device /dev/hdb is write-protected, mounting read-only
mount: you must specify the filesystem type

I tried everything I could gather on the forum and on Google but so far nothing happen. The only result I managed to get was to freeze the computer when I inserted a Commercial DVD.

I'm currently using DVDr+tools 7.0 (but I also tried with 6.0 & 6.1)
KDE 3.5.5
Gentoo-sources-2.6.19-r1
udev
pmount

I have "cdrom cdrw dvd dvdrw" and "cdrom1 cdrw1 dvd1 dvdrw1" in my dev folder but nothing is working.
I tried this in my fstab

Code: Select all

/dev/cdrw1     /media/cdrecorder       iso9660         noauto,users,rw         0 0
/dev/cdrom1       /media/cdrecorder       iso9660         noauto,users,rw         0 0
/dev/dvdrw1      /media/dvdr       iso9660         noauto,users,rw             0 0
/dev/dvd1       /media/dvdr       iso9660         noauto,users,rw         0 0

/dev/sda1              /media/zip      auto            noauto,noatime,user     0 0
/dev/hdb       /media/cdrecorder       iso9660         noauto,users,rw         0 0

with format to "auto"

I have the automount for CD-Rom and CDRW

any help would be greatly appreciated

Check the following...

1) Make sure you have iso9660 support built into the kernel.
2) The CD you are trying to mount has a valid file system on it and not a blank CD/DVD.
3) I have noticed the freezing with commercial DVDs and I think it happens if you don't have dvdcss installed.

Thanks guduri

Yes I have iso9660 in my kernel, and libdvdcss 1.2.9

The CD/DVD I try to read or write are OK, they are readable under windows but when I try with linux I got this message from "dmesg

Code: Select all

hdb: tray open
ATAPI device hdb:
  Error: Not ready -- (Sense key=0x02)
  Incompatible medium installed -- (asc=0x30, ascq=0x00)
  The failed "Read 10" packet command was:
  "28 00 00 00 00 00 00 00 02 00 00 00 00 00 00 00 "
end_request: I/O error, dev hdb, sector 0

In that case all DVDs are considered as Incompatible medium !!!!

By the way I'm running an AMD64 station

You don't need the fstab entries if you are using KDE.

Does this happen with only commercial DVDs? Can you mount/read a previously burned user DVD?

Eugene33 · Post by **Eugene33** » Mon Dec 04, 2006 8:43 pm

Currently I have no entries in the fstab, and only CD/CD-RW is working. Nothing works for DVD/DVD-rw (commercial or others)

Headrush · Post by **Headrush** » Mon Dec 04, 2006 8:56 pm

Can you show the dmesg entry from bootup pertaining to the drive?

Eugene33 · Post by **Eugene33** » Tue Dec 05, 2006 12:12 am

Thanks Headrush
Here the data from my last boot

I also have a SCSI CD-writer and a parallel Iomega ZIP which I can't make work, don't know if it's related

I tend to think this may be a hardware issue. Is this machine a dual boot with Windows? If so, does the drive work normally in Windows?

I have an AMD64 machine and I have a NEC 3540A dvdrw. I have burned numerous cds, dvds with it and had no problems. I don't think AMD64 is a problem

Eugene33 · Post by **Eugene33** » Tue Dec 05, 2006 12:21 am

Sadly with windows it works nicely, I have this problem from a long time and now I really need to use it under linux so I tried to find some solutions, but I could not find anything which could give me a hint on the problem !!!

This may be a long shot but could you post the output of (just to see if there are conflicts)

Code: Select all

dmesg | grep irq

You could possibly compare the irqs to what irqs gets assigned in Windows. That may shed some light.

dmpogo · Post by **dmpogo** » Tue Dec 05, 2006 3:48 am

If you have fstab entry, the syntax is

Code: Select all

mount /mnt/dvdr

or

Code: Select all

mount /dev/dvd

If you want use the full syntax

Code: Select all

mount /dev/dvd /mnt/cdrecorded

will not work, since it needs filesystem type, i.e it should be

mount -t iso9660 /dev/dvd /mnt/cdrecorded

Since you have only one device, it almost certainly linked /dev/dvd, not /dev/dvd1

Thanks dmpogo,
This is the command I use to try to get my DVDs working, but all I have got is this answer for all DVD-RWs (but again those same DVD-RW work perfectly under windows)

Code: Select all

ATAPI device hdb:
  Error: Not ready -- (Sense key=0x02)
  Incompatible medium installed -- (asc=0x30, ascq=0x00)
  The failed "Read 10" packet command was:
  "28 00 00 00 00 10 00 00 01 00 00 00 00 00 00 00 "
end_request: I/O error, dev hdb, sector 64
isofs_fill_super: bread failed, dev=hdb, iso_blknum=16, block=16

And a total freeze with commercial DVD

And I checked the IRQ and it seems that everything is find, same Irq as windows too

UDEV made specific rules too, /etc/udev/rules.d/70-persistent-cd.rules

Code: Select all

# PIONEER_DVD-RW_DVR-106D (pci-0000:00:0f.1-ide-0:1)
ENV{ID_CDROM}=="?*", ENV{ID_PATH}=="pci-0000:00:0f.1-ide-0:1", SYMLINK+="cdrom", ENV{GENERATED}="1"

ENV{ID_CDROM}=="?*", ENV{ID_PATH}=="pci-0000:00:0f.1-ide-0:1", SYMLINK+="dvdrw1", ENV{GENERATED}="1"

and the sysfs path :
/sys/devices/pci0000:00/0000:00:0f.1/ide0/0.1

Everything looks fine but at the end when I insert the DVD, my world crash

dmpogo · Post by **dmpogo** » Tue Dec 05, 2006 3:35 pm

Try to do the following

Idea 1) Switch off dma for hdb

hdparm -d0 /dev/hdb

Idea 2) Boot with kernel option

hdb=ide-scsi

In this case dvdrom will be some scsi device, perhaps /dev/sdb, so fstab lines will be incorrect,
but try to boot manually

If this does not work, move dvdrom to the second IDE controller, so that it is hdc

Eugene33 · Post by **Eugene33** » Thu Dec 07, 2006 10:47 pm

Ok, I deactivated the hdparm but it did nothing, just slowing the freezing !!!
I change hdb to hdc, but still nothing, I checked with windows and it looks like it doesn't work neither.....last time I checked it did, but that was a long time ago, so I'm starting to wonder if it's not a hardware problem.
That's funny because I can read CD-Rom and CD-RW. anyway I will try to clean it and if it still doesn't work I guess i will have to change it !!!!
In that case do you have any advices !?!
