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

Output

**Using the `dd` Command:** 1. **Check the disk device:** Use `lsblk` to identify the disk device you want to wipe. Note down its device path (e.g., /dev/sda). 2. **Unmount the disk:** If the disk is mounted, unmount it using `umount /dev/sda`. 3. **Wipe the disk using zeros:** Run the following command:

1
2
   sudo dd if=/dev/zero of=/dev/sda bs=4M
   
4. **Verify the wipe:** (Optional) You can verify the wipe by checking the disk content:
1
2
   sudo hexdump -C /dev/sda | grep -v 00
   
**Using the `wipefs` Command:** 1. **Check the disk device:** As in step 1 above, identify the disk device you want to wipe. 2. **Unmount the disk:** As in step 2 above, unmount the disk if necessary. 3. **Wipe the disk:** Run the following command:
1
2
   sudo wipefs -a /dev/sda
   
**Using the `shred` Command:** 1. **Check the disk device:** As in step 1 above, identify the disk device you want to wipe. 2. **Unmount the disk:** As in step 2 above, unmount the disk if necessary. 3. **Wipe the disk with random data:** Run the following command:
1
2
   sudo shred -vnz -s 2G /dev/sda
   
Replace `2G` with the size of your disk in gigabytes. **Additional Notes:** * The wipe operations described above will permanently erase all data on the disk. Make sure you have backups before proceeding. * Use the `-v` option in the commands to display progress during the wipe process. * The `-n` option in the `shred` command disables the overwrite pass, making the wipe faster but less secure. * Always consider best practices for data security and disposal when wiping disks.

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

Output

**Using the 'dd' Command:** 1. Boot into a live Linux environment (e.g., Ubuntu Live USB). 2. Find the device path of the disk you want to wipe using `lsblk`. 3. Replace `/dev/sdX` with the appropriate disk path:

1
dd if=/dev/zero of=/dev/sdX status=progress
**Using the 'shred' Command:** 1. Install the `shred` package if not already installed: `sudo apt install shred`. 2. Replace `/dev/sdX` with the appropriate disk path:
1
shred -v -z -n 3 /dev/sdX
**Parameters:** * `-v`: Verbose mode, displays progress. * `-z`: Writes zeros to the disk after deletion for security. * `-n`: Number of passes over the disk (3 is recommended for secure deletion). **Notes:** * Using `dd` with `of=/dev/null` is faster but less secure as it only writes zeros to the beginning of the disk. * Always unmount the disk before wiping it. * Be **very careful** when specifying the disk path, as a mistake can lead to data loss. * The process can take a while, depending on the size of the disk.

Output

**1. List Disks:**

1
sudo fdisk -l
This command lists all the available disks on your system. **2. Identify Target Disk:** Identify the disk you want to wipe by its device name, e.g., /dev/sda for the first disk. **3. Enter Command Mode:**
1
sudo fdisk /dev/sda
**4. Start Wipe Process:**
1
2
o
w
* `o`: Creates a new empty partition table. * `w`: Writes the changes to disk and quit the program. **5. Check Wipe Status:** To verify that the disk has been wiped, issue the following command:
1
sudo dd if=/dev/zero of=/dev/sda bs=4096 status=progress
This command overwrites the disk with zeros, ensuring that it is completely erased. **Additional Notes:** * The `dd` command can also be used to wipe disks directly, without using `fdisk`. However, `fdisk` is generally considered safer. * Make sure to back up any important data before performing a wipe operation. * Once a disk has been wiped, its data cannot be recovered without specialized tools and professional assistance.

**Method 1: Using `dd` command** 1. Open the Terminal. 2. Identify the disk device you want to wipe using `lsblk -o NAME,SIZE,TYPE`. 3. Run the following command, replacing `/dev/disk-device` with the actual device name:

1
2
    sudo dd if=/dev/zero of=/dev/disk-device bs=4M
    
**Method 2: Using `wipefs` command** 1. Install the `wipefs` package if it's not already installed:
1
2
    sudo apt-get install wipefs
    
2. Run the following command, replacing `/dev/disk-device` with the actual device name:
1
2
    sudo wipefs -a /dev/disk-device
    
**Method 3: Using `sgdisk` command (GPT disks only)** 1. Install the `sgdisk` package if it's not already installed:
1
2
    sudo apt-get install sgdisk
    
2. Run the following command, replacing `/dev/disk-device` with the actual device name:
1
2
    sudo sgdisk --zap-all /dev/disk-device
    
**Additional Notes:** * Use the `sudo` command to run privileged operations. * The above methods will wipe the entire disk, including any partitions or data. * If you want to securely wipe the disk, consider using a tool like `shred` or `dban`.

**Using `dd` Command:** 1. **Find the disk to wipe:** Use `fdisk -l` to list the available disks. 2. **Backup any important data:** This process will erase all data on the disk. 3. **Create a zeros file:** Create a file filled with zeros using `dd if=/dev/zero`. 4. **Wipe the disk:** Use `dd` to write the zeros file to the disk. Replace `/dev/sdX` with your disk identifier.

1
sudo dd if=/dev/zero of=/dev/sdX bs=1M
**Using `shred` Command (Secure Wipe):** 1. **Find the disk to wipe:** Same as with `dd`. 2. **Backup any important data:** Same as with `dd`. 3. **Wipe the disk securely:** Use `shred` to overwrite the disk multiple times. Replace `/dev/sdX` with your disk identifier.
1
sudo shred -vfn /dev/sdX
**Using `blkdiscard` Command (For SSDs):** 1. **Find the disk to wipe:** Same as with `dd`. 2. **Confirm that the disk is an SSD:** Check the device's model to confirm that it is an SSD. 3. **Wipe the disk:** Use `blkdiscard` to discard all data on the disk. Replace `/dev/sdX` with your disk identifier.
1
sudo blkdiscard /dev/sdX
**Notes:** * These commands are destructive and will permanently erase all data on the disk. * The time it takes to wipe the disk depends on its size and the speed of your machine. * Once the wiping process is complete, the disk will be empty and formatted as a raw partition. You will need to format and partition it before using it again.
