Hi all,
I was wondering if you have any suggestions on how to fix the click of DVDROM when systems goes to sleep.
I have sleep working well on my Toshiba Sattelite laptop. But when it goes to sleep, it seems the DVDROM is polled every so many seconds and creates this clicking phenomena.
I do appreciate any suggestions or corrections that you may have.
Regards,
Artimess

I actually have this problem while not sleeping, the DVD drive spins up every 15 or so minutes. Any insight would be great.
Hello!
I have the same problem, if there is no disk in the Drive, it will spin up in every 5-10 mins. But i solved with this scripts:
dvd_off.shCODE
#!/bin/sh
sudo kextunload /System/Library/Extensions/IOSCSIArchitectureModelFamily.kext/Contents/PlugIns/IOSCSIMultimediaCommandsDevice.kext
sudo kextunload /System/Library/Extensions/IOBDStorageFamily.kext
sudo kextunload /System/Library/Extensions/IODVDStorageFamily.kext
sudo kextunload /System/Library/Extensions/IOCDStorageFamily.kext
dvd_on.shCODE
#!/bin/sh
sudo kextload /System/Library/Extensions/IOSCSIArchitectureModelFamily.kext/Contents/PlugIns/IOSCSIMultimediaCommandsDevice.kext
sudo kextload /System/Library/Extensions/IOBDStorageFamily.kext
sudo kextload /System/Library/Extensions/IODVDStorageFamily.kext
sudo kextload /System/Library/Extensions/IOCDStorageFamily.kext
If You run the first script, it will ask for You root password, and then disable the DVD drive. It means, the OS will forget about that, and not check anymore. And yes, You can't use Your Drive as long as it disabled. If You want to use it again, You need to enable it with the second script.
The second script will enable the drive, it means, the OS will initialize the drive again, and some seconds later it will be ready for use.
You can hardcode the root password in the scripts, but it not soooo secure.
You can check Your Drive with the "drutil" command. Check below:
