Here's what I can tell you by looking at the error messages don't know if it helps. The driver failed trying to perform a MODE SELECT, which is basically the machine telling the CD drive what type of medium it expects in the drive and what parameters to associate with it. The problem your having is the driver is trying to set a parameter to a value outside a range supported by your drive. Without digging through the source code in detail its difficult tell which parameter it is as each drive has many different "pages" of parameters and the current page is selected by previous command, not shown in your debug output. The only other thing was did you have a cd-rw disc in the drive when you did the cdrwtool command? -- I don't want to sell you any death sticks... I think I'll go home and rethink my life...
