Improve this questionI'm making a utility in C# for a filesystem that isn't supported by windows, which means that I can't just access the drive. I need a way to list all partitions on the hard disk and writing/formatting them.
To list disk partitions you can use WMI.
var searcher = new ManagementObjectSearcher("root\\CIMV2", "SELECT * FROM Win32_DiskPartition");
foreach (var queryObj in searcher.Get())
{
Console.WriteLine("-----------------------------------");
Console.WriteLine("Win32_DiskPartition instance");
Console.WriteLine("Name:{0}", (string)queryObj["Name"]);
Console.WriteLine("Index:{0}", (uint)queryObj["Index"]);
Console.WriteLine("DiskIndex:{0}", (uint)queryObj["DiskIndex"]);
Console.WriteLine("BootPartition:{0}", (bool)queryObj["BootPartition"]);
}
You can use the following approach to get the Volume or DriveLetter on which the partition of disk is mounted.
- Win32_LogicalDiskToPartition
- Win32_DiskDrive
From the Win32_DiskDrive
class you can get the DriveNumber
by querying property Index
or extracting the DriveNumber
from Name
attribute. Then query Antecedent
and Dependent
from Win32_LogicalDiskToPartition
. In the Antecedent
value you will get the Disk Number and the partition it is trying to map the Volume, after that extract the DriveLetter
such as "C:", "D:" etc from the Dependent
property. So by using this logic you can get the LogicalDrives
mounted on particular HardDisk
.
I'm using this logic in my component to get the LogicalDrive
names ("C:", "D:" etc) for particular hard drive on my system.
