Tell me how to wipe a disk from the command line on a macOS machine

Output

**Method 1: Using the `diskutil` Command** * Open Terminal (`Applications` > `Utilities` > `Terminal`). * Identify the disk you want to wipe using the `diskutil list` command. * Note the **disk identifier** (e.g., `/dev/disk1`). * Run the following command, replacing `/dev/disk1` with the disk identifier: 

1
sudo diskutil eraseDisk JHFS+ my-disk /dev/disk1
* Enter your password when prompted. **Method 2: Using the `dd` Command** * **Warning:** This method completely overwrites the disk, making data recovery impossible. * Open Terminal. * Identify the disk you want to wipe using the `diskutil list` command. * Note the **disk identifier** (e.g., `/dev/disk1`). * Run the following command, replacing `/dev/sdX` with the disk identifier: 
1
sudo dd if=/dev/zero of=/dev/disk1 bs=1M
* This command writes zeros to the entire disk, overwriting any existing data. **Method 3: Using a Secure Wipe Algorithm (Optional)** * Open Terminal. * Identify the disk you want to wipe using the `diskutil list` command. * Note the **disk identifier** (e.g., `/dev/disk1`). * Run the following command, replacing `/dev/disk1` with the disk identifier and the algorithm you want to use (e.g., `1-pass`): 
1
sudo diskutil secureErase -type 1-pass /dev/disk1
* Choose from the following algorithms: * `1-pass`: Single pass overwrite with zeros. * `2-pass`: Two pass overwrite with zeros and a random pattern. * `3-pass`: Three pass overwrite with a random pattern, zeros, and a random pattern. * `7-pass`: Gutmann Wipe algorithm (35 passes). **Note:** * Before wiping a disk, ensure that you have backed up all important data. * Wiping a disk is a permanent operation and cannot be undone. * Choose the secure wipe algorithm carefully, as some algorithms take significantly longer to complete.

**Using Disk Utility** 1. Open Terminal.app. 2. Type the following command to list all attached disks: 

1
2
   diskutil list
3. Identify the disk you want to wipe by its `IDENTIFIER`, which will be in the format `/dev/diskX`. 4. Run the following command to wipe the disk securely: 
1
2
   sudo diskutil secureErase 0 diskX
where `diskX` is the `IDENTIFIER` of the disk. **Using dd** 1. Open Terminal.app. 2. Type the following command to wipe the disk with zeros: 
1
2
   sudo dd if=/dev/zero of=/dev/diskX bs=1024k
where `diskX` is the `IDENTIFIER` of the disk.

**Using diskutil:** 1. Identify the disk you want to wipe using the following command: 

1
2
   diskutil list
2. Unmount the disk to prepare it for wiping: 
1
2
   diskutil unmountDisk /dev/<disk_identifier>
3. Wipe the disk using the following command, replacing `<disk_identifier>` with the appropriate value: 
1
2
   diskutil eraseDisk JHFS+ <new_volume_name> GPT /dev/<disk_identifier>
* "JHFS+" is the file system type (Mac Extended). * `<new_volume_name>` is the new name for the disk. * "GPT" is the partition scheme. **Using the hdiutil command-line tool:** 1. Get the device identifier for the disk you want to wipe using the following command: 
1
2
   diskutil list
2. Create a disk image of the disk: 
1
2
   hdiutil create -type UDIF -size 1 -fs HFS+J -volname <new_volume_name> <disk_image_file>
* `<new_volume_name>` is the new name for the disk. * `<disk_image_file>` is the path to the disk image file to create. 3. Mount the disk image:

   hdiutil attach <disk_image_file>
4. Wipe the disk: 
1
2
   diskutil eraseDisk HFS+J "Volume Name" GPT <disk_device_identifier>
* "HFS+J" is the file system type (Mac Extended). * "Volume Name" is the name of the volume to create. * `<disk_device_identifier>` is the device identifier of the mounted disk image. 5. Detach the disk image:

1
hdiutil detach /dev/disk2s1
4. Wipe the disk securely using the command: 
1
sudo hdiutil zerofill /dev/disk2
**Additional Parameters for Secure Wiping:** * **`-passcount`:** Sets the number of passes for secure wiping (default: 1). * **`-secure`:** Performs secure wiping with random data instead of zeros. * **`-verbose`:** Outputs progress information during the wiping process. **Example:** To wipe the disk identified as `/dev/disk2` with 3 passes of secure wiping, use the following command: 
1
diskutil eraseDisk /dev/disk2 GPT JHFS+ myDisk -passcount 3 -secure -verbose
**Note:** * Ensure you have a backup of your data before wiping any disk. * It may take some time to wipe a disk securely, depending on its size.
