Hey guys. I recently installed Snow Leopard on my desktop (ASUS P5QL-Pro motherboard, Q6600 CPU, nVidia 9800GT gpu). Everything works great, except every now and then (like 10 minutes apart), my DVD drive will start to spin up and make noises as if I just inserted a disk... Is there any way I can fix that? This is the guide I used to install OS X: http://www.insanelym...p...aded&start=

Also, this is somewhat unrelated, but I am running a dualboot with Windows 7. Right now I have the Windows 7 bootloader coming up first, and then I can pick from either Windows 7 or OS X. Picking OS X will take me to Chameleon, which lets me boot OS X. This is an easy task usually, but the thing is I used the modified OSInstall.mpkg when I installed OS X so that I could install it on a MBR disk... so there is no EFI partition. What I would like to do is have Chameleon come up first, and be able to boot OS X or Windows 7 (Chameleon is fancier than the Windows bootloader).

Thanks

Known issue. Use the forum search to learn more.

Off the top of my head, four things you can try:

- Disable sleep for hard drives in the energy saver prefs.

- Leave a disc in the drive

- Install this and see if it helps (and please report back!):

- Define the purples!

Yes please give some to me as well! and what the HELL are purples!

thanks for the tips!

Alright, I'm trying that DVD drive modification that should make the drive appear as an Apple one. I'll report back with my findings.

[mrinehart93]

Ok, so the DVD shipping drive modification I tried or w/e did not work. My DVD drive is still recognized as a HP DVD Writer 1260d, and it still spins up randomly.

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.sh

#!/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.sh

#!/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:

Hope it helps.
