My Book Elite 1TB Mac problems

I have a Mac and my Mybook Elite 1TB works fine on my computer but i havent been able to use it on any PC. is there somthing i need to do to make it compatible. i havent tried it on another Mac either but is there a setting i need to change to make my hard drive usable on other computers?

To share data on both Mac and PC computers you need to do these steps below:

Take the drive an plug it back to the Mac computer.

Note: Re-partition the drive will erase all data. Please back up first.

Go to Disk Utility.

Choose the “Partition”

Under “Options” choose “Master Boot Record”

Under Format " choose “MS-DOS (FAT)”

click “Apply” and “Partition”

The drive is now Formatted with Master Boot Record.

It can be read/write from both Mac and PC computers.
