Hard drives advertised as being compatible with Windows and Mac OS may have misled you into thinking you could actually use one hard drive for both computers. You can, but not out of the box. Most external hard drives (HD) are sold in a format called NTFS, which is designed to work with Windows. Macs read and write to a different format, called HFS+. Another format, called FAT32 is compatible with both OS platforms.
Here's a look at how the different HD format types function: FAT32 (File Allocation Table) - Natively read/write FAT32 on Windows and Mac OS X. - Maximum file size: 4GB - Maximum volume size: 2TB NTFS (Windows NT File System) - Natively read/write NTFS on Windows. - Read-only NTFS on Mac OS X - Native NTFS support can be enabled in Snow Leopard and above but has proven instable. - Maximum file size: 16 TB - Maximum volume size: 256TB HFS+ (Hierarchical File System, aka Mac OS Extended) - Natively read/write HFS+ on Mac OS X - Required for Time Machine - Maximum file size: 8 - Maximum volume size: 8EiB Isn't FAT32 the obvious solution?
