Well, I didn't really need to look it up anywhere, since cdrecord already printed the sense key, and the interpretation of the ASC and ASCQ. The sense key is "Medium Error", and the ASC/ASCQ translates to "write error - recovery needed". Presumably cdrecord would have recovered if that were possible. I also looked it up in sys/cam/scsi/scsi_all.c in the sense code table to make sure the error message was the same. Also, if you go to www.t10.org, the SCSI specs are available there. (Draft specs, but generally the final draft is very close to the actual published spec.)
