More diskinfo

Posted by: | July 12, 2017 Comments Off on More diskinfo |

Yesterday I showed how to get the disk, partition and logical disk information using CIM. Today I want to show more diskinfo techniques. This time we’ll use the Storage module which was introduced with Windows 8. Underneath the covers it uses CIM – just different classes.
