wodim broken for CD writing in FC8

[mikeinwales]

I've just upgraded to FC8 from FC5 with a fresh install, now I can't write CDs. Had no problem with FC5 and I've not made any hardware changes.

Sample outputs as root user:

wodim --devices

Same error using K3B or xcdroast.

There was an issue with CD burning in Fedora 7 and as I recall it was related to wodim. There is a thread here that may be of help to you.

Thanks glenzo.

I'd already set wodim suid but i didn't know about cdrdao, so I set that suid too.

I disabled haldaemon and autofs in turn too in case they were accessing the drive mid write. Disabling both gives same result, although I now get some more error info appended:

Errno: 5 (Input/output error), test unit ready scsi sendcmd: no error
CDB: 00 00 00 00 00 00

I'm doing all this from the command line by the way so no K3B issues are involved.

All my drives are IDE, no SCSI or SATA cards/drives exist in the system. I suppose it *could* be a CDRW drive error but strange that it always worked before the upgrade. I may try a live UBUNTU CD later.

You're welcome. I didn't know if this info would help you or not but I thought I'd post it anyhow. There's several threads here dealing with CD / DVD burning issues.

Ah hah! I fixed it... probably.

While messing with drives etc I decided to re-factor the hardware. I had a redundant hard drive (hda) in the system which had windoze on it and also served as the grub boot drive. I no longer have windoze so I took out the drive, spend a hour relabeling partitions and re-installing grub. I also added another CDRW and moved things about generally. Rebooted and tried wodim again. It all works again! I guess my convoluted hardware system was causing the problem. Although, it shouldn't really matter to the OS where stuff is connected it evidently does.

I keep notes in a local wiki. Here's a clip from what I entered about my troubles with GnomeBaker.
Choose Edit > Preferences in the menu, and select the Devices tab. In here, I found my CD drive was detected, but the device file was wrong. It listed it as /dev/sr0 instead of /dev/scd0. All I had to do was click in the field and update the value in there and viola! Fixed her right up. Don't know if this would have helped you. Suppose I could have mentioned it earlier as it sounds like your circumstances are similar.
