That may be the same problem I discovered yesterday together with Joerg Schilling (the cdrecord author). According to him, for several kinds of CD recorders error returns from the recorder are expected by cdrecord (some recorders, for example, return an error for long writes, although they process it (this is allowed by the SCSI spec)). cdrecord handles these error (and they do not turn up as errors to the user), but in order to do this it expectes the CAM layer to return correct sense data after an error (the CAM spec requires the CAM layer to automatically issue a SENSE command after errors). As you can see in the above output, the sense data is all zero, which seems to be broken. At the moment it's not clear, where the problem exactly is: CAM, ATAPICAM or ATAPI. harti AT> AT>scsibus1: AT> 1,0,0 100) 'LG ' 'CD-ROM CRD-8400B' '1.04' Removable AT>CD-ROM AT> 1,1,0 101) 'CREATIVE' 'CD-RW RW1210E ' 'LCS6' Removable AT>CD-ROM AT> 1,2,0 102) * AT> 1,3,0 103) * AT> 1,4,0 104) * AT> AT>Am running as root to avoid any issues there and cdrecord command is: AT> AT>cdrecord dev=1,1,0 5.2-RELEASE-i386-miniinst.iso AT> AT>>From dmesg: AT> AT>pass1 at ata1 bus 0 target 1 lun 0 AT>pass1: <CREATIVE CD-RW RW1210E LCS6> Removable CD-ROM SCSI-0 device AT>pass1: 16.000MB/s transfers AT> AT>Having just read the handbook page, I found I could use the burncd for AT>my ide burner however in the past, I have successfully used the atapicam AT>stuff with cdrecord.
