Hi all,
Over the last couple of days I have been trying to rip some audio CD. This has not gone as smoothly as I had hoped. Applications (Amarok/Rhyumbox/K3b/etc) seemed not to be handling CDs correctly?
So, I went and had a look at my log files. This is a small section of my /var/log/warn file:
May 3 11:09:34 gzunder kernel: [12761.472327] Buffer I/O error on device sr0, logical block 8

This shows a session firstly from an audio CD in an IDE device (/dev/sr0), then from an external USB CD and different audio CD (/dev/sr1). The gray text is the separator.
My assumption from this is that:
a) The media is okay - different audio CDs
b) The drives are okay - different drives
c) The motherboard hardware is okay - IDE and USB interfaces
Any suggestions on where/how to look will be most welcome. I know, the first reaction is to suggest “If it works then its okay”. But I don’t know if the CDs are beeing read corectly or not and I don’t like error logs that can’t be attributed to something.
