Bought a new 500gb WD My Passport External Hard Drive it came formatted NTFS. I'll be plugging it into my MacBook Pro and also my Windows machine and want to read/write files to it from both OS's. From the searching and reading here I've learned the best way to do this is to leave the drive as NFTS and use the NFTS 3G software so I can read and write to it from my Mac and Windows machines. I just want to re-confirm that I was going to format it to FAT 32 but since it's limited to a file size of 4GB (or is it 'folder size of 4GB or more' ?) if it works the nfts 3g software sounds like the best option?
