The Mac OS Extended Volume Hard Drive Format, otherwise known as HFS+, is the file system found on Mac OS 8.1 and later, including Mac OS X. It is an upgrade from the original Mac OS Standard Format known as HFS (HFS Standard), or Hierarchical File System, supported by Mac OS 8.0 and earlier.
These are the Read-Only HFS+ drivers that comes with Boot Camp. They can be installed on any matching Windows Vista, 7, 8, 8.1 or 10 machine without the need to install the Boot Camp package (and also easily removed if necessary). Technically v6.0 should work on Vista/7/8 but it has not been. Attach the hard drive to the system that you wish to format using Mac HFS+ file system.

Question: Q: Journaled HFS (Mac OS Extended Journaled) Hi, I was going to download CAD 2015 (LT) trial vision and they said I need to format my mac to Journaled HFS+ (Mac OS Extended Journaled). The last time I format it I deleted all the data and took me almost three days to figure out.
Overview
Mac OS Extended format (HFS+) is a hard disk format introduced on January 19, 1998, by Apple Inc. to replace their HFS and the primary file system in Macintosh computers and iPod music players.
Mac cannot write to ntfs. Up from HFS, HFS+ increases the number of allocation blocks on the disk and decreases the minimum size of a file, thus optimizing the storage capacity of a large hard disk.

Example:
On a 4 GB hard drive, a file containing 4 KB of information would require 64 KB of space with HFS. With HFS+, it would only require 4 KB on the 4 GB hard drive. This is because the HFS allocation block size would be 16 KB and HFS+'s increased number of allocation blocks of the disk and the decreased minimum size of the blocks allows for less wasted space.
HFS+ also supports much larger files than HFS, with 32-bit block addresses as opposed to HFS's 16-bit length.
It uses Unicode to name files, encoded in UTF-16 and normalized to a form similar to Unicode Normalization Form D (NFD).
HFS+ permits file names of up to 255 UTF-16 characters in length and n-forked files. HFS+ uses a 32-bit allocation mapping table, as opposed to HFS's 16-bit table. Also, unlike most other file systems; HFS+ supports hard links to directories. HFS+ uses B-trees to store most volume metadata.
HFS+ File Limits in Mac OS X:
| Parameter | Value |
|---|---|
| Maximum number of volumes | No limit |
| Maximum number of files and folders in a file | Up to 2.1 billion |
| Maximum volume size and file size: (Mac OS X v 10.0 – 10.1.5) | 2TB |
| Maximum volume size and file size: (Mac OS X v 10.2 – 10.2.8) | 8TB |
| Maximum volume size and file size (Mac OS X v 10.3 – 10.3.9) | 16TB |
| Maximum volume size and file size (Mac OS X v 10.4 and later) | Almost 8 EB |
Basically, the primary difference between Mac data and Windows is in their file systems. While Windows typically uses the NTFS file system, Mac, on the other hand, uses a file system called Hierarchical File System that is commonly abbreviated as (HFS). 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 designed to help in organizing files, data on a Macintosh hard disk. When the hard disk of a Mac computer is formatted, HFS file system supports the creation of a directory so that it can expand forming new folders and files which are added onto the disk. Because HFS has been designed in a Macintosh format, this file system cannot be recognized in windows computers (but doesn't mean you can't recover HFS partitions in Windows).
When it was initially designed, HFS was not made in such a way that it can accommodate high volume hard disk like say those with a mass storage of 100GB and above. Therefore, the Apple's products company introduced a more advanced file system known as HFS+ or the HFS extended that came with the release of Mac OS 8.1 HFS+creates clusters that are smaller or reduced block sizes thus reducing the minimum size taken up by each file. This way, HFS+ has managed to ensure that space is used even more efficiently especially on larger disks. HSF+ is the default file system Mac OS X uses which also supports journaling. This makes the process of retrieving lost data much easier in case a hard drive crash.
So, what is lost HFS or HFS+ partitions on Macintosh OS?
Lost HFS partitions are simply the partitions which get unmounted from the Drive, gone permanently or those that have been deleted accidentally from the Mac Hard Disk leading to massive loss of data. Such partitions can be considered as being lost HFS partitions.
What Are the Reasons That Cause Data Loss from A HFS/HFS+ Partition?
There are various reasons that may lead to a lost or deleted HFS partition (macOS partition). Among them include:
1. HFS partitions lost or deleted due to a massive disk error (fatal disk error)
2. Corruption of a file by virus or directory corruption
An HFS file system can get corrupted as a result of storage devices that are unreadable thus making the stored data unavailable for use. A virus corrupted file system is likely to lead to formatting of the hard drive in order to prevent the virus from spreading to other files.
Here are ways to help in preventing file system corruption:
- Get an updated virus software https://download-matrix.mystrikingly.com/blog/windows-32-emulator.
lock Viruses in order to safeguard your hard drive from viruses by installing your Mac computer with an updated and reliable antivirus. The viruses that are likely to infect your machine in today's arena are both sophisticated and advanced and may cause system breakdown indefinitely.

The file system can get corrupt as a result of improper system shutdown. This is because there is no time for the OS to safely store files in their respective locations. Always avoid premature and sudden computer shutdown as it may end up corrupting your file system.
- Avoid deleting system files readily
Whenever you sense that your drive is almost running out of space, you mat try freeing up space by deleting huge files you no longer require. This can lead you to delete system files that are extremely essential thus corrupting your file system.
- Regularly check your hard drive
Bad hard drive sectors are the main cause of problems on the OS. they can easily cause file system damage. This is why you need to check out for bad sectors and repair them immediately. For instance, Disk Utility is used on Mac while on windows, CHKDSK is used.
- Always remove the hard drive safely
In order to access the external hard drive, you need to connect it to your computer. Later on, when you need to remove it, do so by ejecting it on the computer so as to avoid corrupting the file system.
3. An incorrect format of the file system
Whenever you attempt to open a HFS file and a message prompt appears reading 'incorrect format', most probably the system has been infected by virus or there's a sudden system failure making the file unavailable.

4. Human errors resulting in partitions loss
Human errors can lead to loss of partions like giving the Mac computer a command to format a partition. This is known as accidental formatting or deletion.
5. Removal of BootCamp partition
Whenever a Bootcamp partition is removed inconsistently, it can lead to the loss of valuable spaces of partition so that they can no longer be of use unless the entire Apple drive gets reformatted.
What makes the loss of HFS partition a fatal event?
A missing HDS partition simply means that the data stored in that partition becomes unavailable. Every single file that had been stored in that particular partition goes missing and cannot be traced. In the case where a startup disk gets lost, the Mac user is unable to even merely access the Mac desktop. In other words, loss of a macOS partition makes data that was stored there inaccessible.
