The Diskpart Clean command removes any and all partition or volume formatting from the disk with focus.
Specifies that each and every sector on the disk is set to zero, which completely deletes all data contained on the disk.
On master boot record (MBR) disks, only the MBR partitioning information and hidden sector information are overwritten.
On GUID Partition Table (GPT) disks, the GPT partitioning information, including the Protective MBR, is overwritten. There is no hidden sector information.
A disk must be selected for this operation to succeed. Use the select disk command to select a disk and shift the focus to it.
