What Is Diskpart Clean?

DiskPart clean is a command that removes a disk's sectors, volumes, and data, leaving it in its original, unallocated state. It removes all partitions, files, and data on the disk. When you run the clean command in DiskPart, the partition table and its information are erased from the disk. It makes it look like it was never used before.

DiskPart Clean's main job is to prepare a disk for formatting and splitting. It's often used to start over with a storage device, removing any files and data already there to make room for new ones. People often use DiskPart Clean before loading a new operating system, changing a disk's purpose, or fixing the disk's problems.

DiskPart Clean deletes all data on the selected disk forever, so you must be an administrator or careful when using it. It is a step-by-step guide on how to use DiskPart clean:

  1. The command prompt can be reached by pressing Win + X and then selecting "Command Prompt (Admin)" or "Windows PowerShell (Admin).
  2. Start DiskPart. Put "diskpart" into the command line and press "Enter" to open the DiskPart tool.

Difference Between Diskpart Clean and Clean All

DiskPart Clean and Clean All are primarily different in how much data they delete and how safe they make your computer.

DiskPart Clean

  • DiskPart Clean gets rid of all of a disk's partitions and volumes. It does this by wiping the partition table and information but not eliminating the data.
  • This command lets you quickly prepare a disk for formatting or repartitioning. It can be used to remove current partitions without deleting data safely.
  • Even though DiskPart Clean is quick and easy to use, it leaves the door open for data recovery using specialized software.

Clean All

  • On the other hand, the Clean All program eliminates partitions and writes zeros or a random pattern over the whole disk, deleting all data permanently.
  • This command offers a higher level of security by erasing all traces of earlier data. It can be used in situations where data privacy is essential.
  • However, the Clean All command is much slower than DiskPart Clean because it deletes all files more completely.

Considerations to Think About Before Proceeding with Diskpart Clean:

It's important to think about the following things before running DiskPart clean:

✦ Loss of Data: DiskPart Clean deletes all the data on the chosen disk for good. Before running the command, ensure you have a copy of any critical information.

✦ Disk Selection: Double-check the disk number before running the clean command to ensure you don't accidentally wipe the wrong disk.

✦ System Disk: Do not use DiskPart clean on the disk that holds your operating system; doing so will stop your system from starting.

✦ Recovery: Once DiskPart clean is run, getting back the deleted data is very hard; it usually needs professional data recovery tools and services.
