500gb not recognized on 15 core duo

I just picked up a 500gb samsung HD to replace my stock 100gb drive.

I installed the new drive & OSX but when it tries to start up there is only a black folder with a question mark. I've tried reformatting and reinstalling about 3 times with no luck.

The computer works fine when I reinstall the old 100gb HD. The 500gb drive seems to work fine as an external, but will not boot OSX!

Do the core duos have an issue with large drives? Do I have a software or hardware problem?

Thanks!!!
 
I installed a samsung 500gb drive (from newegg) in my 2.16 CD, everything went fine. I just used the leopard install disk utility to setup 1 partition and it worked from there. Not sure what partition table it was set to though.

My money says you did not choose GUID partition table when you initialized the drive.

Probably right, the only other option is that he didnt format the drive in HFS+ or an Apple compatible format. Theres no issue with the computer reading a 500GB drive.

To be fair it's quite impossible to format it wrong when you use the installation DVD for OS X.
 
-The drive is internally installed.
-The drive is recognized externally, but will not boot externally. (without partition)

The drive was formatted by the OSX CD using Mac OSX (Journaled).

I tried creating 3 partitions (145/145/172 give or take), then installed OSX on one of the 145 partitions and the installation worked perfectly. Im actually using the laptop in question now.

So, as I'm typing this I went into disk utility and removed the other partitions. Now my startup drive says its capacity is 465gb. good.

Could the OS be having a problem recognizing the drive on startup? I'm a little worried about restarting my computer!
