I mistakenly ordered the WD My Passport Ultra drive for Windows instead of My Passport for Mac. Rather than send it back, I'd like to format it for my MacBook Air. The problem, is I've never done this. For the most desirable results when reformatting on Windows systems, use Western Digital's Formatting Utility. Due to a system limitation, Windows 2000, Windows XP and Windows Vista can only create 32GB FAT32 partitions, regardless of the drive's capacity.
My Passport Ultra was previously used on my Windows 7 PC. I have since reformatted it on my PC just to get all the info off of it. I want to format it to work on my Macbook Pro for Time Machine, so I looked into how to do that. It told me to open the Disk Utility, and to choose the drive and then choose 'Erase'. However, the 'Erase' button is greyed out and it will not let me erase it. Again, the drive has already been formatted on my PC, so it is blank.
