Q: Optical Drive, DVD Disappear after sleep

Weird problem.   My DVD and inserted disk disappear from the desktop after several hours or after sleep and awake.  The inserted disk cannot be seen by Disk Util, but the Optical Drive can be seen.  When I press the eject button on the keyboard, the eject icon appears on the screen but does not open the drive. The optical drive Eject option is greyed out in Disk Util, so that won't work, Neither can it mount.  I can get it to open and be recognized by restarting the computer and holding down the mouse key, but having to do that every time I want to use the drive is not a solution.  This behavior only started happening in the past week.   I'm in Snow Leopard 10.6.8

    Oddly,  I fired up Parallels 7 and connected the Drive and was able to see the disk contents and eject the disk. I then disconnected it again from Parallels and the Mac then saw the disk again.  Parallels was not running when the problem occurred and it has not been updated recently.

    I know this is an old thread but I have this problem as well. 

    I have a MacPro v5.1 with the cd/dvd tray and the original internal Pioneer DVD drive.

    If I insert a new disk when one is not present, the DVD mounts just fine.

    It is only after putting the machine to sleep at night or having it go to sleep on its own do I have problems.

     

    After waking up from sleep mode, if there is a DVD disk in the internal DVD drive, the DVD drive and disk are not mounted.

    They have disappeared from the finder.

    The DVD drive and disk are not shown in the sidebar of the finder. 

    They are not shown on the desktop of the finder.

    The keyboard eject button does not work even thought there is a DVD disk in the drive.

    Opening up an appliation (DVD player, iTunes, Disk Utility) does not help.

    The drive and DVD disk do not show up in iTunes and Disk utility to mount them.

    If I start up the DVD player, an error message appears: "There was an initialization error.  A valid DVD drive could not be found. [-70012]

     

    Relaunching the finder does not help.

    I know restarting the computer works.

    However, I have having  to constantly restart the computer after sleep so that the internal DVD drive is mounted with its disk inside.

     

    I tried staring up parallels desktop (v9) suggestion above but this did not work either.

    With parallels desktop, I tried recognizing the drive but it did not work either.

    At least parallels does see the drive.

     

    I have tried looking into many of the CD ejection methods, including using the terminal commands.

    None of these seem to work if the DVD drive is not mounted. 

    I don't want to physically pull out on the DVD tray for fear of damaging it.

     

    I am open to other ideas - please don't say just restart the computer because I know this works.

    original internal Pioneer DVD drive.

    I doubt that a Pioneer drive is the original. Most systems used drives by HL-DT-ST. Pioneer drives were a popular replacement drive.

    In the system profiler under disk burning I show:

    HL-DT-ST DVD-RW GH41N:

     

    It further indicates:

    Burn Support: Yes (Apple Shipping Drive)

     

    Disk utility indicates:

    Disk Description: SuperDrive

    Burn Support: Apple Shipping

     

    However, I don't think (HL-DT-ST DVD-RW GH41N) indicates the manufacturer.

    I think Parallels Desktop shows the proper manufacturer of the internal hard drive..

    OK.  I guess others are indicating it is a Hitatchi drive.

    I suspect my problem is related to  DVD framework that many are commenting about.

    When the computer wakes from sleep, the DVD framework is probably not refreshed.

     

    I have also read some people having issues with an old program called MACFUSE and old files that remained installed after an upgrade.

    However, I doubt that is an issue when I do fresh clean installs.

    It's a LG DVD drive.

    OK. 


    Now I see:

    HL-DT-ST  =   HITACHI-LG -  DATA -  STORAGE

    Someone on the web suggested using the Toast application to force the operating system to recognize the disk and the drive. 

     

    "What's always worked for me is to launch Toast, set it to do a Disc Copy - it will recognize the disc in the drive either as a good or bad disc, but in either case it will allow you to click 'eject' in Toast - and the held disc ejects..."  Authored by: beeyoot on Mar 03, '10.


    I don't have a current copy of Toast to try this.
