Red Hat Bugzilla – Bug 219489
cdrecord fails, invalid multibyte character
Last modified: 2008-05-06 13:10:53 EDT
Description of problem: When I type cdrecord -scanbus, I get the error message: cdrecord: Invalid or incomplete multibyte or wide character. Cannot open SCSI driver. This happens both on my desktop and laptop computers (both run FC6). Version-Release number of selected component (if applicable): rpm -qa |grep cdrecord cdrecord-2.01-10 How reproducible: cdrecord -scanbus Actual results: Error message, "Invalid or incomplete multibyte or wide character. Cannot open SCSI driver." Expected results: A list of all my cd/dvd drives Additional info: The problem is solved by overwriting /usr/bin/cdrecord with the binary from FC5's cdrecord-2.01.01.0.a03-3.i386.rpm.
scanbus? why? just use the device name, and yes, "-scanbus" should be removed.
The -scanbus option is documented in the manpage for cdrecord. If it is no longer a valid option, then an error message like "invalid option" would be better. If one should now use device names directly, then it would be great to include an example of this as the first one in the EXAMPLES section of the manpage.
I am having the same problem on the two FC6 machines I run. I agree whole-heartedly with Anders in comment #2. If scanbus is no longer appropriate, the man page should reflect this.
Upgrade FC5-i386 to FC6-x86_64 (first of all NEVER upgrade like this because it just messes up the system, so I installed from scratch). OK. I was burning CDs and data DVDs OK with k3b. cdrecord -scanbus worked too as far as I recall. Then I went to burn some MP3s to an audio CD. Well, we all know what happpened. Redhat and Fedora don't support MP3 playback (which is PERFECTLY legal). So, I downloaded a bunch of libraries (like livna) to get mp3 playback and burning working. But, when I went to burn my CD with k3b, it died. I went to command line and got this bug now. I cannot scanbus, nor can I burn. Bizarre, I was burning data DVDs under k3b, now I can't even get anything command line working. Strace shows that not much is happening, cdrecord dies before making any library calls (as far as I can tell.) So, what gives? Malware???? Installed, FC5_x86_64 cdrecord and have scanbus working again. I don't have time at the moment to try burning my dvd again. Will try later.
This problem is also happening on my FC6 systems. -scanbus is a necessary option. I have many scripts written that just -scanbus to build list of media devices. You can almost get it working with: cdrecord -v -scanbus dev=ATA This works for 2.6 kernels. The problem then becomes that you sometimes get a listing and sometimes it just hangs. So really there is a bug in cdrecord for Linux that needs fixing. The fact that you can get a listing is proof that the command is operational. The main problem lies in the fact that sometimes the command (with dev=ATA) will hang either with a partial listing or it hangs right away.
> sometimes the command (with dev=ATA) will hang either with a partial listing or it hangs right away _sometimes_ seems to me as it is a hardware problem..
Doubtful. I have many other programs that work just fine on the same hardware. growisofs for example. I just burned a dozen backup DVD's on this same hardware without any problems at all. And I used K3B yesterday on the same machine to burn some other DVD's. It had no problems either.
