If you know you’re going to use a drive on both Mac and Windows, you should use the exFAT file system, which is compatible with both. But if you didn’t foresee that, you may have formatted your drive with Apple’s HFS Plus, which Windows can’t read by default.
A nice treatment of what journaling does is in retired Technical Note TN1150: HFS Plus Volume Format. The journal area on the file system is written heavily and forces the OS to hard sync data on a regular basis. Modern Mac versions have advanced to a new file system format called HFS plus as a replacement of the conventional HFS file system. In this article, I will provide a step-by-step guide on recovering HFS/HFS+ partition but before then, let's have a look at deeper details on the HFS file system. What Really is a HFS or HFS+? HFS is a file system. Mac OS Extended. Choose one of the following Mac OS Extended file system formats for compatibility with Mac computers using macOS 10.12 or earlier.

Disk Utility on Mac supports several file system formats:
- Apple File System (APFS): The file system used by macOS 10.13 or later.
- Mac OS Extended: The file system used by macOS 10.12 or earlier.
- MS-DOS (FAT) and ExFAT: File systems that are compatible with Windows.
Apple File System (APFS)
Apple File System (APFS), the default file system for Mac computers using macOS 10.13 or later, features strong encryption, space sharing, snapshots, fast directory sizing, and improved file system fundamentals. While APFS is optimized for the Flash/SSD storage used in recent Mac computers, it can also be used with older systems with traditional hard disk drives (HDD) and external, direct-attached storage. macOS 10.13 or later supports APFS for both bootable and data volumes.
APFS allocates disk space within a container on demand. The disk’s free space is shared and can be allocated to any of the individual volumes in the container as needed. If desired, you can specify reserve and quota sizes for each volume. Each volume uses only part of the overall container, so the available space is the total size of the container, minus the size of all the volumes in the container.
Choose one of the following APFS formats for Mac computers using macOS 10.13 or later.
Hfs Plus For Mac Os
- APFS: Uses the APFS format.
- APFS (Encrypted): Uses the APFS format and encrypts the volume.
- APFS (Case-sensitive): Uses the APFS format and is case-sensitive to file and folder names. For example, folders named “Homework” and “HOMEWORK” are two different folders.
- APFS (Case-sensitive, Encrypted): Uses the APFS format, is case-sensitive to file and folder names, and encrypts the volume. For example, folders named “Homework” and “HOMEWORK” are two different folders.
You can easily add or delete volumes in APFS containers. Each volume within an APFS container can have its own APFS format—APFS, APFS (Encrypted), APFS (Case-sensitive), or APFS (Case-sensitive, Encrypted).
