The Disk Management utility that comes with Microsoft Windows operating systems can be used to view details of drives and partitions in the system and attached to the system via USB. To start the utility, you can type diskmgmt.msc in the Windows search field, which you can access by clicking on the magnifying glass icon at the bottom of the screen on a Windows 11 system or by typing diskmgmt.msc in the Type here to search field on a Windows 10 system. To use the utility, you must run it as an administrator, so if you are not logged into an administrator account, you need to right-click on the utility when you see it returned in the search results and choose "Run as administrator".
