Formatting VS Erasing (Is formatting or erasing permanent data deleting?)

Formatting, is to make a media a new place for data storage that you may change its file system while you format it. Formatted drive data would be marked as available for new data to take its space.

There are three levels of formatting

  1. quick format (no disk error checking and repairing)
  2. full format (includes repairing bad blocks)
  3. low-level format (it could only be performed by professional low level format tool, which is usually shorten the life of device)

Erasing, is to remove information on your device, which is more simplier than formatting, however it is not true wiping out all the information since erased files could be restored with help of free data recovery software.

Well, the truth is data could also be destoryed if you continue using your device after the formatting or the erasing and saved a huge number of files. If no data was saved to formatted/erased media, data could still be restored with professional tools.

How to erase data permanently on mac with freeware

Since erased files or erased media could still be recovered in Mac Disk Utilities and WD Disk Utlities, you may want to query how to erase data permanently on Mac? Is there any freeware that could do the permanent deleting?

The answer: BitRaser is a 30 days free program for erasing files permanently on Mac, we failed to find other free tools for the permanent erasing at this time.

Disk Utility can find and repair errors related to the formatting and directory structure of a Mac disk. Errors can lead to unexpected behavior when using your Mac, and significant errors might even prevent your Mac from starting up completely.

Before proceeding, make sure that you have a current backup of your Mac, in case you need to recover damaged files or Disk Utility finds errors that it can't repair.

Open Disk Utility

In general, you can just open Disk Utility from the Utilities folder of your Applications folder. However, if your Mac doesn't start up all the way, or you want to repair the disk your Mac starts up from, open Disk Utility from macOS Recovery:

  1. Determine whether you're using a Mac with Apple silicon, then follow the appropriate steps:
    • Apple silicon: Turn on your Mac and continue to press and hold the power button until you see the startup options window. Click the gear icon labeled Options, then click Continue.
    • Intel processor: Turn on your Mac, then immediately press and hold these two keys until you see an Apple logo or other image: Command (⌘) and R.
  2. You may be asked to select a user you know the password for. Select the user, then click Next and enter their administrator password.
  3. From the utilities window in macOS Recovery, select Disk Utility and click Continue.

Select your disk in Disk Utility

Choose View > Show All Devices (if available) from the menu bar or toolbar in Disk Utility.

The sidebar in Disk Utility should now show each available disk or other storage device, beginning with your startup disk. And beneath each disk you should see any containers and volumes on that disk. Don't see your disk?


In this example, the startup disk (APPLE HDD) has one container and two volumes (Macintosh HD, Macintosh HD - Data). Your disk might not have a container, and it might have a different number of volumes.

Repair volumes, then containers, then disks

For each disk that you're repairing, start by selecting the last volume on that disk, then click the First Aid button or tab.


In this example, the last volume on the disk is Macintosh HD - Data.

Free Mac Disk Repair Tools


Click Run to begin checking the selected volume for errors.

  • If there is no Run button, click the Repair Disk button instead.
  • If the button is dimmed and you can't click it, skip this step for the disk, container, or volume you selected.
  • If you're asked for a password to unlock the disk, enter your administrator password.

After Disk Utility is done checking the volume, select the next item above it in the sidebar, then run First Aid again. Keep moving up the list, running First Aid for each volume on the disk, then each container on the disk, then finally the disk itself.


In this example, the repair order is Macintosh HD - Data, then Macintosh HD, then Container disk3, then APPLE HDD.

If your disk doesn't appear in Disk Utility

If Disk Utility can't see your disk, it also can't see any containers or volumes on that disk. In that case, follow these steps:

  1. Shut down your Mac, then unplug all nonessential devices from your Mac.
  2. If you're repairing an external drive, make sure that it's connected directly to your Mac using a cable that you know is good. Then turn the drive off and back on.
  3. If your disk still doesn't appear in Disk Utility, your Mac might need service. If you need help, please contact Apple Support.
