Well, Windows users may not need to format the external hard drive but, mac users should format the hard disk to make it compatible with mac.

There are several reasons to store data in an external hard drive. However, external hard drives are used as professional means to give a protected backup to essential data. Because data play an important role in finance and other services business companies.

What is a Mac Compatible file system?

There are various filesystems. Every filesystem is compatible with an operating system. So, here we are going to describe all about different types of filesystem and the compatibility with the operating system. Because you should know about filesystem before formatting external hard disk drive on mac. Otherwise, you may face problems. Moreover, you may lose your important data.

FAT32 (MS-DOS FAT)

It is the enhanced version of the classic and original FAT filesystem. So, FAT stands for File Allocate Table. However, the reason behind its name is that it holds track of all your file in the storage device and helps the computer to place the file from the storage area. Even in the case of disk defragment, the files are kept on track for allocation.

FAT32 helps the computer to allocate data from smaller clusters of the hard drive. Hence, it increases the efficiency of the Hard disk. You should know that FAT32 supports up to 2 terabytes. So, if your data is more than the limit is not FAT32 is not recommend for you. Bear in mind, if you are using PC and Mac you can use and format data up to 4GB or less in FAT32 file format. So, if you are using only mac them check out the rest.

Ex-FAT

It stands for Extensible File Allocate Table. Ex-FAT is compatible with Mac and Windows. So, Ex-FAT does not allow limitations like FAT32. Thus, it can store data more than 4GBs. Moreover, Mac operating systems offer both the read and write support for Ex-FAT. That’s why users prefer Ex-FAT over FAT32. So, Ex-FAT is usually used for external storage devices that are plugged into both Mac and Windows.

NTFS

New technology file system the full form of NTFS. So, it is the advanced filesystem that Microsoft uses for the new operating systems to store and retrieve data while engaged with the hard drive. However, NTFS is mostly used for non-removable storage drives. As it is the default file system of the MS. Windows So that by default mac users are allowed only to read data from the NTFS file system.

HFS+ (MacOS Extended)

It is the macOS Extended mostly called the HFS(Hierarchical File System) plus or HFS+. This file system is being used since January 19, 1998, for Mac operating systems and all drives. It is the enhanced version of HFS as it can in place more data as compare to HFS.

But, Apple updated the file system with the release of the macOS Sierra. Hence, HFS+ is replaced by AFPS. Bear in mind, you can encrypt your data using macOS Extended(Journaled, Encrypted). or if you use macOS Extended (Journaled, Case Sensitive) then on Windows you have only the read option, So there will be no write option for you.

APFS (Apple File System)

 

MacOS Siera brings this File System. So, if you are using older versions Macintosh operating system then you have to work with HFS+. Although, APFS is reliable and more efficient. So, it is enhanced for SDD (solid-state disk) drive and USB Flash drives.

Well, Windows and Linux can not read the APFS drive by default. So, if you are using only mac APFS, I recommend you to use AFPS. In case, you are using both Windows or Mac or Linux then the good choice for you is Ex-FAT.
