This is the best format if you intend to use LaCie USB 3.0 Drive with Time Machine.ĪPFS (Apple File System)-An Apple file system optimized for solid state drives (SSDs) and flash-based storage systems. Windows cannot natively read or write to HFS+ (journaled) volumes. Mac OS Extended (HFS+)-The native hard drive file system for macOS. macOS can read NTFS volumes but cannot natively write to them.

While you can fix minor problems on all three file systems with fsck, you will have to use MS Windows to fix anything major. Consider splitting the drive into two partitions. A large NTFS partition for data that is more stable, as well as read/write on Windows and Linux. A small exFAT partition to copy files from Mac OS.įAT32. Read/write on all three systems.
