You can use this and still share FAT32 volumes with a PC, but if you’ll primarily be using the drive with Windows, and if the full capacity of the drive doesn’t exceed 2TB, the wiser course is to wipe the drive and then use Windows’ Master Boot Record (MBR) partition scheme.ģ.

By default, Mac OS X will use the GUID partition table to format the drive. Click the Partition button in Disk Utility’s main window. To create a new partition, click the drive in the list on the left side of the Disk Utility menu. You can format the remaining space as a second FAT32 partition or as an HFS+ partition, or you can leave it as unallocated space. Mac OS X won’t let you create a FAT32 partition larger than 2TB so if your drive is larger than that, you’ll need to divide the available drive capacity into multiple partitions. We’re going to do this anyway, so open Disk Utility from the prompt or by navigating to /Applications/Utilities.Ģ. If the drive is not formatted, you may get a message saying that the drive is unreadable by Mac OS X and asking you whether you want to format it via Disk Utility.

Macs running Snow Leopard or Lion can read from drives formatted as NTFS, but they can’t write to such drives unless you install a third-party driver or muck about in the Terminal. Windows prefers to use NTFS (which stands for New Technology File System, though it has been around for nearly 20 years now). Finally, Mac OS X’s Time Machine backup utility won’t work with FAT32. When formatting partitions, Windows 7’s Disk Management utility won’t let you create one that’s larger than 32GB, whereas Mac OS X Lion can create partitions as large as 2TB using its Disk Utility application. So if you work with bulky video clips, for example, adopting FAT32 may not be a good idea. FAT32 imposes a size limit of 4GB on single files. The chief drawbacks of FAT32 involve file and partition size limitations. Though this format has some limitations, it enjoys nearly universal support from active platforms, including Mac and Windows operating systems, and many gaming and Linux OSs.
