On GUID partition table (GPT) disks, the GPT partitioning information, including the Protective MBR, is overwritten there is no hidden sector information. On master boot record (MBR) disks, only the MBR partitioning information and hidden sector information are overwritten. Removes any and all partition or volume formatting from the disk with focus. Please ignore low level format definition and how low level format remark bad sector, I already know that.Ĭlean all does everything that clean does, but all data is zeroed (securely erased) so that it's not recoverable. I need to know what is Diskpart doing in background. In essence, on Windows run the following from the command prompt (where is the number of the desired disk): diskpart list disk select disk clean create. I need to confirm whether Diskpart could remove bad sectors or not because I have to care NAS in my job. So I think that Diskpart is doing same thing like official HD utilities, that mean Diskpart may remove or repair bad sectors. Some official hard disk utilities has "Quick" and "Full" zero same as Diskpart "Clean" and "Clean All", and hard disk zeroing action is performed by hard disk firmware, that means no matter what software we use, they are doing same action in background. According to Microsoft official document, "Clean All" command is perform "Write Zero" action on hard disk too. And the function usually called "Fill Zero" or "Write Zero", and there is one command called "Clean All" in Microsoft Diskpart. As I know many hard disk vendors provide official disk utilities for remove or repair bad sectors for permanently. There is a question confuse me for a long time.
