    By "snap disc", I wanted to say "slot-in" ...

  • BDAqua Level 10 Level 10 (120,380 points)

    It would appear to be not completely comatible, but have we tried this yet?

     

    Before sleep or standy...

     

    Open Console in Utilities & see if there are any clues or repeating messages when this later happens.

    In my experience with hundreds of different Macs coming into our facility each year,  using standby is the cause of many problems.

     

    We  never use standby or sleep as it disconnects the video cards and drives out of our ststem.

     

    To me if everything is working well from a standard boot, never use standby or sleep, just shut the Macdown properly after working on the machine. In our conference suite, if a Mac sleeps during an interval, the optical drive, Keynote, Quicktime player never work properly untill its re-booted.

    Interesting, thanks, I've not seen Optical dropping, but nowhere near your experiences in numbers!

  • castanou34 Level 1 Level 1 (0 points)

    Using Console in Utilities seems to be a very good idea !

     

    --> Indeed, here is the report of Console when the standby or sleep mode is ok (when the optical player is not seen by the MBP) :

    ... etc

     

    and the last message is displayed constantly !!

     

    Should I deduce that this optical player is not fully compatible ?? while the original one must necessarily be ...

  • BDAqua Level 10 Level 10 (120,380 points)

    OK, good work, off hand, that seems like a Hardware problem with the Disk or Disc.

     

    Boot off your *original* Install Disk while holding down the *d key*, (not c key), then run the extended Apple Hardware Test. Some disks require you to use the Option key at bootup to select AHT. Some Discs have it inexplicably on Disc #2. Some models have a separate AHT CD.

  • castanou34 Level 1 Level 1 (0 points)

    Done this day ! but after the long AHT analysis, approximately 90 minutes, no pb was identified by this test.

     

    I was so surprised by this result that I made many tens of regular boots, and I found - via the Disk Utility tool - that the MBP supports the DVD player in a really random way, so regardless of any standby !!

     

    Thus one might think that the AHT analysis was carried out in a case where the DVD player wasn't take into account ...

     

    And furthermore I didn' need to use the original Install Disk, cause holding down the d key at the Boot without inserting the Leopard was enough to launch the Apple Hardware Test.

     

    --> Is it possible to force the launch of this AH test from the CD, when hoping in my case that I will be lucky enough to be in the good case (with the DVD player being seen ...) ??  via d & c key ??

  • BDAqua Level 10 Level 10 (120,380 points)

    I don't think AHT checks the Optical drive, in fact I've seen where the Hard Drive was bad & AHT just skipped the HDD test completely.

     

    Furthermore, If it does check it & finds it not there, it'll likely skip that test... & tell you everything is hunky dory.

  • castanou34 Level 1 Level 1 (0 points)

     

     

    Any other clue to go on ? 

     

    I am very surprised by the random feature I observed, when starting the MBP whith the Regular Boot ...

  • castanou34 Level 1 Level 1 (0 points)

    To summarize, I think you were absolutely right when you said that the current Toshiba-Samsung DVD player is not fully compatible.

     

    But the question remains: is this a hardware problem? that does not explain a priori the random effects observed about supporting or not the DVD player ... or is it a software problem, ie a feature restrained by Apple, that does not allow to use anything other than Apple Certified disk players ... ?? but it's very surprising that we are not able to bypass this restriction ...  tell me ...

     

    Thanks !

  • BDAqua Level 10 Level 10 (120,380 points)

    Might not be a case of restricting, more likely it would be support for talking to it isn't inclided, but, the random nature seems like some hardware timing issue.

     

    I forget, is this an IDE or SATA Optical?

  • castanou34 Level 1 Level 1 (0 points)

    Does this mean that the only solution is to try with an "Apple proof" DVD player ?

     

    About your last question, it's maybe SATA, but I am not sure. It is the same as the one of step 11 of the following tutorial :

  • BDAqua Level 10 Level 10 (120,380 points)

    Hmmm, maybe this one, are there any jumpers on yours?
