Secure Erase Solid State Drive

Is Secure Erase Necessary

As you know, the new Mac models ship with Solid State Drives (SSDs). According to Apple, the Secure Erase and Erasing Free Space will be not available in the Disk Utility. They are not needed anymore since the standard erase action makes it very difficult for others to recover your data intentionally. Therefore, you only need to do a simple erasing on your SSD.

How to Secure Erase SSD on Mac

Some people still want to perform secure erase on their SSDs, ignoring Apple’s word. They should open Terminal and type diskutil secureErase freespace VALUE /Volumes/*.

  • The word VALUE should be replaced by a number between 0 and 4, representing different erasing methods.
  • The symbol * represents the name of the target drive.
