>After using cdrecord for over a year without incident, I have recently
>begun to see SCSI command timeouts during the fixating portion of
>writing a CD9660 data disk. The disk is still mountable upon completion,
>but only on a CD-RW drive. The output from cdrecord is below.
>These errors occur with both CD-R and CD-RW disks from different
>manufacturers. The hardware configuration has not been changed at all,
>and I have checked the SCSI cabling many times. The CD-RW drive has been
>flashed to the latest firmware release. I don't know whether this
>is at all relevant, but the problem seemed to begin shortly after the
>changes to libcam in May-99, after remaking world and updating the
>cdrecord port.
>I have also seen similar command timeouts while trying to blank
>a CD-RW disk with the "blank=fast" option.
>I would be interested if anyone else is experiencing similar problems.
