I just purchased my first macbook and bought a 500GB LaCie Hard Disk Designed by Neil Poulton external hard drive. When I was formatting it with my PC, it asked me to partition the drive so I can use it with a Mac but I noticed that it only let me partition 32GB for a Mac and the remaining 468GB was for Windows. This is also my first time using an external hard drive so this is all new to me. Can I only backup 32GB total from a Mac? Am I only able to transfer 32GB from my PC to my Macbook? If so, is there anything I can do to partition more storage space for the Mac? Any help will be much appreciated, thanks!
