Hi,
I've got problems burning CDs using cdrecord. I've scsi-emulation, general scsi support, etc. compiled into kernel and everything seems okay:

bash-2.05b# cat /proc/scsi/scsi
Attached devices:
Host: scsi0 Channel: 00 Id: 00 Lun: 00
Vendor: TEAC Model: CD-W516EB Rev: 1.0B

Host: scsi0 Channel: 00 Id: 01 Lun: 00
Vendor: PIONEER Model: DVD-ROM DVD-106 Rev: 1.22
Type: CD-ROM ANSI SCSI revision: 02

I've got also cdrecord -scanbus working nice:

Blanking CD-RW seems to be working:

No errors so I suppose everything is ok..

So I properly read that message above and ... here am I
I've also tried to compile another kernel with scsi as modules and tried to burn using ATAPI and I was even able to burn CDs, but it was never succesful - it stopped during the process. But since ATAPI libscg is pre alpha i dont find it as a mistake between keyboard and monitor.. :-) Burning works fine with windows + nero, so hardware shouldn't be broken..

Thanks for your time

I have hit the same problem occasionally. In my case I can get around the problem by changing:
cdrecord blank=fast dev=0,0,0
to
cdrecord blank=all dev=0,0,0

I've tried to blank the entire CD as you recommended and got these errors:

I've noticed "status: 0x2 (CHECK CONDITION) " so i tried the burn process one more time with brand new cd and the error were the same.. It seems Gentoo does not want me to burn any other distribution :-)

I am at a lose as to what your problem is.

The fast erase sometimes creates a bad spot at the end of the erase and full erase did not fix the problem.

Sometimes you have a bad CD-RW but you have tried several CD-RWs, including a new one with the same results.

Sometimes you get a bad drive which may or may not be fixable by cleaning the heads but Windows Nero works OK.

I suggest that you try a CD-R and see what happens, not because I particularly expect it to work but because it may give you a different clue as to what the problem is.

I've tried many CD-Rs or CD-RWs, but the error was the same.. i've got it working today using 2.6-beta-test9 kernel+ATAPI burning (scsi-emulation even was not compiled) and it worked, but i have found some problems using 2.6 kernel, so im trying to make brand new configuration for 2.4.23-pre8..
I have made 4 new kernels today and still same problem.. maybe it has something to do with the version of gcc im using (3.2.3).. it looks i will have to wait until 2.6 is definetely out.. :o)

Dear Folks: I have been having the same problem with DVD & CD burning. Always with errors. Nothing I do seems to work. Occasionally I get a CD burned without an error. Always the DVD is burned with errors. I have yet to burn a DVD without errors. I have tried everything I know: ide-scsi emulation, setting the permissions different with K3b setup, and logging in as root and using both K3b and Xcdroast. Nothing works. I have an AMD Athlon 64 3400 processor with a MSI K8T-NeoFSR2 motherboard [MS-6702] with 1 GB of RAM and 2 CD/DVD combo burner drives: a Lite-On and an Optorite drive and nothing seems to work! I am running Fedora Core 2 the 32-bit version with the 2.6.5-1.358 kernel and nothing seems to work. It does not matter what kernel I use as the result is the same. I give up. I even tried Fedora Core 3 but it was so buggy and flawed I had to go back to Fedora Core 2 until Fedora Core 4 comes out as I had too many problems with Fedora Core 3 [which is garbage and should be junked]. Any ideas anyone? I may have to install Windows just to get some DVDs & CDs to burn without errors although I purely HATE Windoze.
