Hi,
the result of scgcheck command is (much long):

For the next test we need to open a single SCSI device.
Best results will be obtained if you specify a modern CD-ROM drive.

This may be because the firmware in your drive is buggy.
If the current drive is not a CD-ROM drive please restart
the test utility. Otherwise remove any medium from the drive.
