Does initializing a disk erase data on Mac? The answer is Yes, and initializing a disk on your Mac means formatting it. When you initialize a device, you make it usable by the macOS. When you erase a device/file, you remove the contents. Initializing a disk previously used with an incompatible format will inherently erase the disk.

Disk Utility on macOS has the option of a secure erase, which will erase data on your disk, optionally many times. File recovery after this is effectively impossible.

However, initializing a disk alone does not preclude recovering the erased data by advanced means, such as professional data recovery tools, EaseUS Data Recovery Wizard for Mac.

It can recover Disk Utility erase. Follow the steps below:

Step 1. Install and open EaseUS, and choose the erased disk on your Mac.

Step 2. Click 'Scan' to view all the erased data on the disk.

Step 3. Select the recoverable data and click 'Recover' to get them back.

In addition, you can back up the essential data from the disk before you format it. For example, you can use iCloud, Time Machine, external hard drives, and other cloud-based devices. After initializing your Mac disk, you can restore the erased data from your backups. Follow the steps below to restore from Time Machine:

Step 1. Start Mac in Recovery Mode.

Step 2. Click 'Continue' on the Restore from Time Machine page. Select your Time Machine backup drive to proceed.

Step 3. Restore the data of your Mac disk by selecting the drive and clicking on 'Restore', and then restart your Mac when it is finished.
