Diskpart Command 'Clean' vs 'Quick Format' Command?

clutchc · Dec 30, 2016

What does the Diskpart 'clean' command do that the the Win 'quick format' command doesn't? How are they different? I read competing views on this. I understand that the clean command leaves the disk in need of initializing in Win. But other than that.

That was my understanding. Quick format will delete partition data, and clean will delete the partition table itself I believe is the underlying difference.

diskpart clean

Removes any and all partition or volume formatting from the disk with focus. 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.

all
Specifies that each and every sector on the disk is zeroed, which completely deletes all data contained on the disk.

Quick Format
"When you choose to run a Full format on a volume, files are removed from the volume that you are formatting and the hard disk is scanned for bad sectors. The scan for bad sectors is the reason why the Full format takes twice as long as the Quick format.

If you choose the Quick format option, the format removes files from the partition, but does not scan the disk for bad sectors."
