[ASK]Drive Wont Accept the Disc except in Windows Mode

Hi,

i just bought a new modded Mini Mac 5,2 with built in an optical drive.
About a couple weeks a go, the drive wont accept the disc except :
1. I put the disc 1st when booting
2. Im in Windows Mode using bootcamp

If i use the 1st condition, it will read the disc normally. It even will do installation of Mountain Lion. And when i eject the disc (in OSX mode), and re insert the disc several times (about 3 times), it will still take it. But usually after the 4th insert, it wont feed the disc anymore.
And also, if the drive stays in idle or no disc in it, the problem will start. The drive wont feed the disc.

If i use the 2nd condition, the drive works fine and flawlessly.

So, the problem will only occur when i use the OSX mode and didnt put the disc when booting.

Anyone ever have this kind of problem ?

Thanks before.

@omnius : if its not connected properly, why in windows mode the drive works fine.

Im still looking for this problem. If this is the HW issue, i suppose to have the same problem on windows right ?
Software ? Is there anything related to EFI update ?

Today, i just updated the EFI to EFI 1.6. And the problem still there.

And also, i found a new "weird behaviour" with the drive. I can make the drive feed the disc without the need to restart the mac and put the disc into it. The drive will feed my disc if i click the System Preferences => CDs & DVDs icon.

I think there is something related to waking up the drive. But i can't find how to set or modify the waking up the drive option. Anyone here ever had this kinda problem ?

Thanks
