Formatting 3TB Elements Desktop Hard Drive by Western Digital for mac osx 10.5.8

I just bought my external hard drive from b&H and I read that it says:

Windows XP, Vista, 7; Mac OS X 10.4, 10.5, 10.6
USB 2.0 port

Note : In order to use a drive larger than 2 TB, you will need an operating system that can partition and format that drive. Windows 7, Vista, Windows XP (64-bit), Mac OSX 10.4.x (Tiger), Mac OSX 10.5.x (Leopard), Mac OSX 10.6.x (Snow Leopard), and Mac OSX 10.7.x (Lion) all have this capability through the GUID Partitioning Table (GPT). The GUID partitioning scheme has the ability to partition both internal and external drives far beyond 2 TB’s in size.

But my computer cant read it, I can fromat it and use it!

Hello,

If the drive is not seen when you connect it to your computer please try:

 

1- Connecting the power adapter to the wall outlet directly.

2- If the computer is a desktop, connect it on the back USB port (directly to the computer port, not through a hub).

3- Go to disk utility, and verify if the drive is seen.

-If it is seen in disk utility then click on the link below to get information how to format it.
