Why to Format Mac Hard Drive?

Formatting a Mac Hard Drive could be very helpful for various factors like in preparing the startup disk to reinstall macOS to sort out the mess spread on the system. Formatting is also proved helpful in correcting the corruption or unreadable errors occurring for the storage drive. As Mac offers various different formats, formatting a system can be important to change the file system format for cross-compatibility with various other formats. Formatting can also repair the storage device when the Disk Utility fails to fix it.

However, the entire process of formatting Mac systems involves a lot of risk as the data could accidentally format forever too.

In case of an external hard drive, if it is a corrupt or unreadable drive, then the system will ask to initialize the disk which should NOT be done in order to save data from getting lost. Although if it is empty or there is a backup of the data on the drive, then it is safe to initialize.

What is the correct way to format Mac drive?

  1. Take backup: Before formatting a Mac hard drive, take backup of all the data which can either be in an internal or an external hard drive. In case the Time Machine Backup is not set up, then this is the time to set it up so that it can save a backup of the data for recovery in future.
  2. Format the Startup Disk in macOS Recovery Mode: Mac could be formatted without losing any data with the help of following steps:
  • Restart Mac and immediately press and hold ‘Command’ + ‘R’ keys.
  • Release the keys when Apple’s logo or a spinning globe pops on the screen.
  • The MacOS Utility window will pop up.
  • Click ‘Disk Utility’ and then ‘Continue.’
  • In the Disk Utility window, choose ‘Show All Devices’ under ‘View.’
  • Select ‘Macintosh HD’ from the left panel and then click ‘Erase.’
  • Provide the required information in the new tab and then again click ‘Erase.’
  • Once the format is complete, close the app.
  • Restore data from Time Machine Backup.
  • Reinstall macOS.
  1. Format a Mac External Hard Drive using Terminal: In case Disk Utility doesn’t let the external storage device to be erased, these steps can help formatting it using a terminal:

Before starting the process, make sure the data is backed up.

  • Open Spotlight by pressing ‘Command + Space Bar.’
  • Type ‘terminal’ and press ‘Return’ which will launch the Terminal application on the macOS.
  • Type ‘diskutil list’ in the Terminal window.
  • Type ‘diskutil eraseDisk FS DN D#’

(Here, FS should be replaced with the required file system format; DN stands for the name of the drive, and D# for the drive’s identifier.)

  • Once the process is complete, the data could be restored from the backup.
