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

Output

Wiping a disk from the command line on a macOS machine can be done using the `diskutil` and `dd` commands. Here's how you can safely and effectively wipe a disk: ### Step 1: Identify the Disk First, you need to find the identifier of the disk you want to wipe. 1. Open Terminal. 2. Type the following command and press Enter:

3. Identify the disk you want to wipe from the list. It will have a name like `/dev/diskX`, where `X` is the disk number. ### Step 2: Unmount the Disk Before wiping, you need to unmount the disk: Replace `/dev/diskX` with your actual disk identifier. ### Step 3: Wipe the Disk You can use either `diskutil secureErase` for a secure wipe or `dd` for a general wipe. #### Option 1: Using `diskutil secureErase` 1. Use the following command to securely erase the disk. The number after `secureErase` represents the erase level: - `0`: Single-pass zeros - `1`: Single-pass random - `2`: US DoD 7-pass secure erase - `3`: Gutmann algorithm 35-pass secure erase Example for a single-pass zero erase: #### Option 2: Using `dd` 1. To write zeros over the entire disk: 2. To write random data (optional, for better security): **Note:** Using `dd` is generally less secure than `secureErase` for non-SSD disks but can be useful for quick wipes or overwriting with specific patterns. ### Step 4: Verify After the wipe, you can verify that the disk is blank by listing the disks again: ### Important Considerations - **Data Loss Warning**: Both methods will permanently erase all data on the target disk. Make sure you have backups if needed. - **Admin Privileges**: You'll need administrative privileges to run these commands. You may be prompted to enter your password. - **Incorrect Disk Choice**: If you choose the wrong disk, you could erase important data. Double-check the disk identifier before proceeding. By following these steps, you can securely wipe a disk on macOS from the command line.

To securely wipe a disk on a macOS machine using the command line, you can use the `diskutil` command. This command-line utility allows you to manage disks and volumes. Follow these steps to erase a disk: 1. **List All Disks:** Open the Terminal application and enter the following command to list all available disks:

This will display a list of all storage devices connected to your Mac, including USB drives and internal disks. Identify the disk you want to erase by noting its identifier, such as `disk2`. 2. **Unmount the Disk:** Before erasing, make sure the disk is unmounted. You can do this by running: Replace `diskX` with the actual disk identifier (e.g., `disk2`). 3. **Erase the Disk:** Once the disk is unmounted, you can erase it using `diskutil`. There are several options for formatting a disk, but a common and straightforward method is to format it as HFS+, APFS, or ExFAT. Here's a command to format it as HFS+ (Mac OS Extended): Replace `'DiskName'` with the desired name for the disk, and `diskX` with the actual disk identifier. 4. **Securely Erase Free Space (Optional):** If you want to securely erase the existing free space or the entire disk to ensure that data recovery is not possible, use the `secureErase` option. This might be useful if you're dealing with sensitive information. The number `0` stands for a single-pass erase. If you require a more thorough erase, you can replace it with: - `1` for using a multi-pass (or more secure) erase. - `2` for using the U.S. Department of Energy multi-pass. - `3` for a Gutmann algorithm 35-pass erase. Note that secure erasing takes considerably more time than a standard erase, especially with higher numbers of passes. 5. **Verification:** Once complete, you can verify that the disk has been erased by listing the disks again: Always double-check that you have the correct disk identifier before performing any erase operations to avoid data loss on unintended drives. ### Important Note Be absolutely sure that you have backed up any important data from the disk before you proceed, as these operations will erase all data on the specified disk, making recovery impossible.

Wiping a disk on a macOS machine can be done using the command line tool `diskutil`. This operation involves erasing all data on the disk, so it's crucial to ensure that you’ve backed up any important information before proceeding. Here’s a step-by-step guide: 1. **Open Terminal:** You can find Terminal in Applications > Utilities, or by searching for it in Spotlight (Cmd + Space, then type "Terminal"). 2. **List Available Disks:** Enter the following command to list all connected disks and their identifiers:

This command provides information on all the disks available, allowing you to identify which disk you want to wipe. Look for a line corresponding to the disk you want to erase, usually in the format `/dev/diskX`, where `X` is the disk number. 3. **Unmount the Disk (if necessary):** If the disk is currently mounted, you may need to unmount it before wiping. Replace `diskX` with the correct disk identifier: 4. **Erase the Disk:** Now, use the `diskutil` command to erase the disk. You can specify the file system format and a new name for the disk. The example below uses `JHFS+` (Journaled HFS Plus, Mac OS Extended) as the file system format, but you can choose other formats like `APFS` for newer Mac systems. Replace `diskX` with your actual disk identifier: - `JHFS+` is the file system format. - `DiskName` is the new name you want for this disk. - `/dev/diskX` is the disk identifier. 5. **Securely Erase the Disk (Optional):** If you require a secure erase (overwriting the data to prevent recovery), you can use the `secureErase` option instead. The level of security ranges from `0` to `4`: The levels are: - `0`: Single-pass, writes zeros - `1`: Single-pass, writes random data - `2`: US DoD 7-pass secure erase - `3`: Gutmann algorithm, 35-pass - `4`: US DoE standard, 3-pass **Important**: Securely erasing can take a long time depending on the size of the drive and the level of security you choose. 6. **Verify:** Once the process is complete, you can verify by using `diskutil list` again to ensure the disk has been erased and is now appearing in the desired format. Remember, these actions will irreversibly erase all contents on the specified disk. Ensure you have selected the correct disk by double-checking its identifier, and confirm that you have backups of any important data before proceeding.

Wiping a disk from the command line on a macOS machine can be done using the `diskutil` and `dd` commands. It's critical to ensure you are selecting the correct disk to avoid data loss on the wrong volume. Here’s how you can do it: ### Using `diskutil` 1. **List the Disks**: First, list all the disks to identify which one you want to wipe.

2. **Unmount the Disk**: Before wiping it, make sure the disk is unmounted. Replace `diskX` with your target disk's identifier (e.g., `disk2`). 3. **Erase the Disk**: Use the `diskutil` command to securely erase the disk. Replace `FORMAT` with the desired file system format (e.g., `APFS` or `JHFS+`), `DISKNAME` with the desired name for the disk, and `diskX` again with your target disk's identifier. For a more secure erase option, you can use: - The number `0` in `secureErase` specifies a single-pass erase (faster). You can choose levels from 0 (fastest) to 4 (most secure). ### Using `dd` for More Advanced Use 1. **Zero Out the Disk**: This method writes zero to the entire disk. This can take a significant amount of time depending on the size of the disk. Replace `diskX` with your target disk's identifier. 2. **Wipe with Random Data**: For greater security, write random data over the disk. Note: This process can take even longer than zeroing out the disk. ### Important Considerations - **Double-check the Disk Identifier**: Always double-check the `diskX` identifier to ensure you do not accidentally erase the wrong disk. - **Admin Privileges**: These operations often require sudo privileges, so you may be prompted to enter an administrator password. - **Backup Important Data**: Ensure you have backed up any important data before wiping the disk. This process will erase all data on the disk, making data recovery very difficult or impossible, so proceed with caution.

Here are the steps to do this: 1. **Open Terminal**: You can find the Terminal application in Applications > Utilities. 2. **List All Disks**: First, you'll need to identify the disk you want to wipe. Use the following command to list all available disks and their identifiers:

This will provide a list of all disks, including their identifiers like `/dev/disk1`, `/dev/disk2`, etc. 3. **Identify the Target Disk**: Carefully identify the disk you want to wipe by checking its size and partition scheme. Double-check to ensure that you don't accidentally erase the wrong disk. 4. **Wipe the Disk**: Use the `diskutil` command to erase the disk. Be extremely careful with this command to ensure that you specify the correct disk identifier. Replace `/dev/diskN` with the identifier of the disk you want to erase. For example, to erase the disk and format it with the APFS filesystem, you might use: If you want to securely erase the data, you can use `secureErase` with a zero-filling option. Secure erase options are usually more time-consuming but ensure that the data is irretrievable: You can replace `0` with other levels of secure erase (from 0 to 4) depending on how securely you want to erase the data: - `0`: Single-pass zero-fill erase. - `1`: Single-pass random-fill erase. - `2`: US DoD 7-pass secure erase. - `3`: Gutmann algorithm 35-pass secure erase. - `4`: US DoE 3-pass secure erase. 5. **Confirm and Wait**: Confirm the action if prompted, and wait for the process to complete. **Warning**: This will irreversibly erase all data on the specified disk. Make sure you have backups of any important data before proceeding. Handling disk operations can be risky, so proceed with caution and ensure you are targeting the correct disk.
