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

Output

Here are a few methods to wipe a disk from the command line on macOS: 1. Using `diskutil`:

# First, list all disks to identify the target disk
diskutil list

# To perform a single-pass zero fill (quick but less secure):
diskutil eraseDisk JHFS+ DiskName /dev/diskN

# For a more secure 7-pass erase:
diskutil secureErase 2 /dev/diskN

# For the most secure 35-pass erase (very time-consuming):
diskutil secureErase 4 /dev/diskN

2. Using `dd` command (basic zero-fill):

# Replace diskN with your target disk number
sudo dd if=/dev/zero of=/dev/diskN bs=1m

Important notes: - Replace 'diskN' with your actual disk number (e.g., disk2) - Be VERY careful with disk numbers - wiping the wrong disk is irreversible - Always backup important data before wiping - Make sure the disk is unmounted before wiping - You'll need administrator privileges (sudo) - The secure erase options take significantly longer than a basic erase For safety, double-check the disk identifier using `diskutil list` before proceeding with any wipe operation.

Here are two methods to wipe a disk from the command line on macOS: 1. Using `diskutil`:

# First, list all disks to identify the one you want to wipe
diskutil list

# To securely erase the disk (replace diskX with your disk identifier)
diskutil secureErase 0 /dev/diskX

# For a simple quick erase (not secure, but faster)
diskutil eraseDisk APFS "DiskName" /dev/diskX

2. Using `dd` command (more low-level):

# Replace diskX with your disk identifier
sudo dd if=/dev/zero of=/dev/diskX bs=1m

Important notes: - Always make sure you have the correct disk identifier - Be extremely careful as these commands are irreversible - Replace "diskX" with the actual disk number (e.g., disk2) - The disk must be unmounted before erasing - You'll need administrator privileges (sudo) - For external drives, use diskX (like disk2) not diskXsY (like disk2s1) The `diskutil secureErase` command has different security levels (0-4): - 0: Single pass of zeros - 1: Single pass of random data - 2: US DoD 7-pass secure erase - 3: Gutmann algorithm 35-pass secure erase - 4: US DoE 3-pass secure erase The higher security levels take longer but are more secure.

Here are a few methods to wipe a disk from the command line on macOS: 1. Using `diskutil`: First, list all disks to identify the one you want to wipe:

1	diskutil list

Then use one of these commands: For a quick erase (less secure):

diskutil eraseDisk JHFS+ DiskName /dev/diskN

For a secure erase (multiple passes):

diskutil secureErase 2 /dev/diskN

Where: - JHFS+ is the format (Mac OS Extended) - DiskName is your chosen name for the disk - /dev/diskN is the disk identifier (replace N with the number from diskutil list) - 2 is the security level (0-4, where 4 is most secure but takes longest) 2. Using `dd` (be very careful with this command):

dd if=/dev/zero of=/dev/diskN bs=1m

IMPORTANT: - Always double-check the disk identifier before wiping - Make sure you have backups of important data - Be extremely careful as these commands permanently delete data - Never wipe the disk containing your operating system while it's running Replace 'diskN' with your actual disk number from the diskutil list output.

# Then use diskutil to erase the disk (replace diskX with your disk identifier)

# First, identify the disk
diskutil list

# Unmount the disk
diskutil unmountDisk /dev/diskX

# Wipe with zeros
sudo dd if=/dev/zero of=/dev/diskX bs=1m

Important notes: - Replace `diskX` with your actual disk identifier (e.g., disk2) - BE VERY CAREFUL with these commands - using the wrong disk identifier can erase the wrong drive - JHFS+ can be replaced with other formats like: - APFS (Apple File System) - MS-DOS (FAT) - ExFAT - The `dd` command provides a more secure wipe but takes longer - Always backup important data before wiping any disk For added security, you can also use a multiple-pass wipe:

diskutil secureErase 4 /dev/diskX

The number 4 represents a 7-pass erase. Options are: - 0: single-pass zeros - 1: single-pass random - 2: 7-pass DoD - 3: 35-pass Gutmann - 4: 3-pass DoD

# To wipe with zeros

# To wipe with random data
dd if=/dev/urandom of=/dev/diskN bs=1m

Important notes: - Replace `diskN` with your actual disk number (e.g., disk2) - Be EXTREMELY careful to select the correct disk number - Make sure you have backups of any important data - You need sudo/root privileges for these commands - The disk must be unmounted first (use `diskutil unmountDisk /dev/diskN`) For additional security options with `diskutil secureErase`: - 0: Single-pass zeros - 1: Single-pass random - 2: US DoD 7-pass secure erase - 3: Gutmann algorithm 35-pass secure erase - 4: US DoE 3-pass secure erase Example of a complete secure wipe:

sudo diskutil unmountDisk /dev/disk2
sudo diskutil secureErase 2 /dev/disk2
