In this Windows 10 guide, we will walk you through the steps to use the DiskPart tool to clean and format a hard drive to fix data corruption and other problems. If you have multiple drives connected to your device, it's recommended to disconnect them to avoid selecting the wrong device. If the drive is still accessible, it's recommended to back up the data before proceeding. These instructions will help you use DiskPart on either partition style.Īlso, these instructions will erase everything on the selected drive, and you cannot undo the changes. You usually would want to use GPT, but MBR is also acceptable for external drives.
The difference between the two is that GPT is meant to replace MBR since it supports more than four partitions on a drive, and it's required on drives with more than 2TB of storage. The GPT is a newer partition style usually found in Unified Extensible Firmware Interface (UEFI) devices.
The MBR is the legacy partition style for the standard Basic Input/Output System (BIOS). It's worth noting that you can have different types of partition styles, including Master Boot Record (MBR) and GUID Partition Table (GPT). On Windows 10, when an external drive (USB flash drive, SD card, or secondary drive) stops working due to data corruption or another logical problem, you can use the DiskPart tool to erase everything and start with a new partition.ĭiskPart is a command-line tool designed to manage drives, partitions, volumes, and virtual disks using Command Prompt, which usually works better than other Windows 10 tools, such as Disk Management and the Format feature available in File Explorer.
