Trouble whith a VERY hard-to-read CD causes kernel errors

Hi guys!
Sorry to bother you if this is worthless, but I'd like to report that my 
kernel spits out lots (about every one or two minutes) of packet command 
errors at the (3-hour) read of a quite damaged cd. A sample:

hdc: packet command error: status=0x51 { DriveReady SeekComplete Error }
hdc: packet command error: error=0x51
ATAPI device hdc:
Error: Illegal request -- (Sense key=0x05)
Illegal mode for this track or incompatible medium -- (asc=0x64, ascq=0x00)
The failed "Read CD" packet command was: 
"be 04 00 01 da 5d 00 00 08 f8 00 00 "

This is right in the middle of the CD, and cdparanoia (with -z) displays 
unreported loss of streaming and stays at some single sectors for about half 
an hour.
I am using cdparanoia III release 9.8 (March 23, 2001) on a SuSE 8.0 system 
whith kernel  2.4.18-4GB and using an ATAPI CD-drive.

The basic starting point for cases like this is to use ide-scsi instead 
of ide-cd .  The SCSI interface gives cdparanoia a much more verbose 
interface to work with.

In fact, really you should be using SCSI emulation for any use of 
cdparanoia.  It's just better.

I don't know if it'll actually help in this case, but it might.

Never heard this advice before. Is there some technical info I can
look at which lends weight ? I don't want to start advising people
to use ide-scsi without reasons to back up the claim that it's
better.

Cheers,
Rik

This has been standard info/practice for at least a year or two, or more.
Check http://www.xiph.org/, I am sure I have read it somewhere (with
authority) before, and I am guessing that is where I read it.

I'm quite puzzled ..

I'm trying to get cdparanoia to work, but it won't.  I don't have any of
the sg* block files in /dev/ and I figure out how to get them. I'm using
debian 2.0.38 . The drive is a scsi NEC at /dev/scd0 .

cdparanoia III release 9.8 (March 23, 2001)
(C) 2001 Monty <monty <at> xiph.org> and Xiphophorus

Report bugs to paranoia <at> xiph.org
http://www.xiph.org/paranoia/

/dev/cdrom exists but isn't accessible.  By default,
cdparanoia stops searching for an accessible drive here.
Consider using -sv to force a more complete autosense
of the machine.

More information about /dev/cdrom:
Checking /dev/cdrom for cdrom...
        Testing /dev/cdrom for cooked ioctl() interface
                /dev/scd0 is not a cooked ioctl CDROM.
        Testing /dev/cdrom for SCSI interface
                No generic SCSI device found to match CDROM device
/dev/scd0

Re: I'm quite puzzled ..

i remember having this problem years ago.... i _think_ the solution is to
recompile your kernel with "generic SCSI support".

best,

Track 0 Failure ?

I see this has come up in the mailing list and I was just checking whether you 
were aware of it ?  

cdparanoia does not seem to read track 0 of CD's successfully where as I can 
read it OK with various ms windows apps.

I have tried both versions 9.3 and 9.8 without success and I am trying to cure 
myself of a microsoft addiction so any advice would be appreciated,

regards

rob beattie

(red hat 2.4.18-3 / Toshiba SD-r1002 1034)

PS otherwise excellent program which successfully reads damaged Cd's which 
nothing else even comes close to reading. Keep up the good work, much 
appreciated.

Project Status

The web page says once Ogg 1.0 is out you will revive working on 
cdparanoia. Is that still the plan? Is this being ported to Mac OS X?

Keep up the good work and thanks for the info

Status?

I'm trying to figure out whats going on with paranoia IV.
It's been almost 18 months since the last cdparanoia release.
Even the Sopranos took less time to get a release out.

Is this project dead or not?

[paranoia] [PATCH] fix for possible crash in cdda_identify_scsi() (interface/scan_devices.c)


Hi!

I hope this is not the wrong list here as my mail concerns a patch for 
paranoia III, but as I got no response on the user list, I'll try here:

I always got a SIGSEGV in a KDE cd burning tool (k3b) after turning off my 
SCSI-scanner. 

With the help of SuSE, I now found out that the crash was caused by 
cdparanoia-III-alpha9.8.

Please see the attached patch - NULL value of the result of scsi_inquiry() 
wasn't checked correctly which lead to a SIGSEGV in strncmp() naturally...

If this is also not the right place to send patches to, please tell me what it 
is... ;-)

Ciao,

Gernot
