Hello all, I just bought a WD MyBook 500gb external hard drive, I needed it since i have recently switch from a PC to a new MBP and had to ship a lot of files over. I left the drive in FAT32 while I did this, but can still see myself needing to transfer files between the two in the future as well. But, since I've done the main bit of transferring, i deleted the files on the drive and want to use it with Time Machine but also have the possibilty of using it in the future to transfer files from PC to mac. So now looking at using time machine on it, i would like to know what File type to format the hard drive? FAT32 or ...? Please help guys as i am new at this and have ever used an external HD before or time machine. Thanks!
