What Is Low-Level Format?

Low-level formatting is the next step up from standard formatting. In a standard format, the data is simply erased and you can always restore it using any recovery software. However, if you want to completely destroy data and prevent data leakage, low-level formatting is your best choice.


A low-level format starts by formatting the disk drive. It then packs the remaining space with a zero value, causing the data to be permanently deleted. In this case, after your data is deleted, others cannot access or recover it. On this page, we will show you how to do low-level format in Windows 11 with Diskpart, a command-line utility used to manage hard disk partitions and volumes.
