Comment(by maverik044 <level42 at sympatico.ca>):

 Attached is a patch that fixes eject with drives managed by the kernel
 SCSI driver.  If the drive is managed by the SCSI driver (/dev/scdx) and
 returns status CDS_TRAY_OPEN, this patch uses ioctl to send a packet to
 the drive to query its status.

 Packet format is per "Mt Fuji Commands for multimedia devices" SFF8090i,
 version 1.0 and therefore independent of the kernel.  The only thing I
 can't test is BIG_ENDIAN machines, the structure format in the code is
 correct, I just don't know if the right includes files are there for
 WORDS_BIGENDIAN to be defined.

 I mentioned previously that there is a kernel driver patch floating around
 for this.  I would like to add that it has been since around 2.6.11 of the
 kernel, and never made it in the kernel, not even the recent 2.6.23
 release.  Therefore I assume it will never be for some reason.  Thus
 requiring this patch as all IDE/ATA/SATA devices are managed by the SCSI
 driver in recent kernels (by default) unless specifically configured
 otherwise.

 This should partially fix the above problem as the "Unable to open orclose
 the empty drive xxxx (/dev/scd0). You may have to use the eject button on
 the drive" message is the same I get for my Pioneer drive.  This patch
 fixes that.  I suspect that skd5aner also has a problem with the locking
 function of the drive from Myth.
