[gentoo-user] Porblem with dvd+rw-tools

[Meino Christian Cramer]

Hi,

 I got strange problems (probably) with dvd+rw-tools-6.1-r1:

 There are three files (recordings from my DVBT-receiver):

-r--r--r-- 1 root root 1205874688 Jul  2 10:14 2006-04-02_20-15_Ice_Age.mpg
-r--r--r-- 1 root root 1492150272 Jun 30 20:29 2006-06-27_22-15_Twister.mpg
-r--r--r-- 1 root root 1754710016 Jun 30 18:20 2006-06-28_20-15_Final_Fantasy.mpg

 which I burned with k3b onto a DVD+RW media.
 The process itsself does not produce any problems. Even the
 verify-function reports "Success".

 Then I ejected the medium, reinserted again, mounted the DVD and
 cat * > /dev/null all files.

 Result:
 cat: 2006-06-28_20-15_Final_Fantasy.mpg: Input/output error

 The kernel log files contains this:

        Jul  2 14:38:49 [kernel] attempt to access beyond end of device
        Jul  2 14:38:49 [kernel] hdd: rw=0, want=8388608, limit=8388604

        Jul  2 14:38:49 [kernel] Buffer I/O error on device hdd, logical block 2097151
 
 K3b was instructed not to produce a multisession DVD and not to use
 UDF-structures.

 Strange enough, I can repeat this with another medium and get back
 the same block reported in the log files.

 Now...

 Then I used dd  to read the whole DVD in one go. The read process as
 such completes without any error. So I think medai and burner are
 not guilty for this.

 However when cat'ing the files from the image, which I mounted via
 loop-device, I got the same error as those described above.

 The I used readcd to perform the same thing, mounted the image via
 loop-device ans VOILA! the files could be read with correct sized
 files from the image without any error.

 I could repeat the experiment by using growisofs from the comandline
 with comparable results (the files were written in a different order,
 though).

 An image generated with k3b (which then does not use growisofs) is
 ok.

 Here I stand, head in hand, turn my face to the wall....

 I have simply no clue, who or what is playing bad jokes at me...

 My system:
 Gentoo Linux (32bit) with vanilla kernel 2.6.17.3 (newest stable)
 dvd+rw-tools 6.1
 mkisofs 2.0 (as reported by growisofs)
 k3b 0.12.6 

 Hardware:
 AMD64 X2 3800+
 1GB RAM
 Asus AV8 motherboard
 LG 4163B (firmware A106, newest release) DVD/CD-Burner


 Any help to resolve the problem described above is very appreciated.
 Thank you !

 Kind regards,
 mcc

Hi,

is the problem still there after a reboot?

I had a similar problem. sometimes after a successfull burn, I would not be 
able to mount the dvd or reading from it gave me errors. Rebooting helped.

I don't know why, but it solved it ...

No, unfortunately, that does not help in any way.

What is so wrong here?

are you burning with udf support enabled?

*scratch* AFAIR there was a problem with certain filesizes when burnt without 
udf. But I am not sure.

It should be worth a try.

Or maybe the blank has gone bad? But dd should give errors in that case too... 
hm...

Enabling UDF results in the problems...

sigh...

I mailed the author of dvd+rw-tools but no reply until now.
I subscribed to the cdwriter-mailinglist. The mailinglist server
tells me, it will send me a confirmation mail for the subscription.
None received until now...

Am I lost ?

Any other chance?

Desperate...

and do you have udf in the kernel?

hm - mailserver are sometimes slow. Maybe you should retry it tomorrow.

Did it work with a normal blank?
