There are lots of people who mistakenly think that the USB drives and hard drives format don’t really matter. But the reality is quite different. Whether it is a hard drive or USB or internal drive, Mac uses different format support. So, you can’t simply use the same drive with both Windows and Mac.

The basic operation is termed as low-level formatting which means erasing the existing data on the disk. But it leaves the track to recover the data using the recovery tool.

There is another term related to disk formatting and it is called reformatting. It is called high-level formatting as it is used to prepare the disk for different file system formats. It is usually done during the OS installation or adding a new disk. Reformatting is done to free the storage space from the previous content stored in it.

You can consider disk formatting in macOS in various circumstances. Whether your system has corrupted data, damaged software, impending system upgrade, storage is full, or it is running slow, formatting will fix a lot of issues. Take a look at the scenarios given below and you will be sure that disk formatting will help you.

  • If you want to resolve a disk issue that can’t be fixed by the Repair feature of Disk Utility.
  • If the macOS installer can’t see the disk or unable to install it.

Part 4. Different Formats of Hard Drive for Mac:

Mac Hard drives have wide support for formats but there are two major formats that are preferably used by the Mac users. It also depends on the macOS version you are using. The key point to consider is that the drives formatted with the newer versions won’t be recognized by the older devices. So, when you are formatting a USB drive, it will be ideal to choose the right format which is Mac OS Extended.

The supported Mac formats for the drive are explained below:


The APFS format is optimal for Solid State Drive such as flash drives. Hence, if you are formatting a flash drive, you should definitely choose the APFS format. Along with the flash drives, this format is also faster and more reliable for Mac hard drives.

Mac OS Extended:

Talking about Mac OS Extended, it is perfectly suitable if you want to use a drive for backup. The Time Machine feature of Mac still doesn’t have support for APFS disk. In case you select this format, Time Machine will prompt you to reformat the drive.

When you are formatting disk on Mac, keep some things in mind. Never ever change the inbuilt format of a Mac drive.

Part 5. Tips for Formatting a Hard Drive on Mac:

Even though formatting doesn’t seem like a big deal, still it can be very helpful. So, you must stay active and keep all things in mind. Here are some tips that might help you when you are about to format a Mac hard drive.

  • Disk Utility in macOS Sierra and later chooses a compatible format for you automatically. But you should know the default format for your drive. It is advised not to change the default format of a Mac hard drive under any circumstances.
  • You can check the format of a drive inside the Disk Utility Menu bar. Just click on the Get Info option and you’ll know the current format a drive is using to store files. Open the System information and select the storage. In the right-side panel, you will see the respective format for each volume on your Mac.
  • If you want to erase your disk before you install the latest High Sierra on your Mac for the first time, then opt-out for the Mac OS Extended format. During the installation of OS, the macOS installer will automatically decide whether to use APFS or Mac OS Extended for the disk.
  • You can also use the FAT32 format on Mac for USB drives if you wish to use it on both Mac and Windows. The FAT32 format can be read and written on both OS and hence it is the most versatile format for use.
  • If you wish to transfer big files from Windows to Mac, you’ll still have an alternative, i.e. exFAT. This format doesn’t have a file limit but it can only be read on Mac OS X Snow Leopard or later.

So, before you pick out the format, look out for the advantages and the disadvantages of the formats to choose the optimal format for Mac. The Windows supported format is usually listed as an MS-DOS format in the list of formats.
