Win32 API P-Invoke to bring a disk online, offline, and set unique ID

Question

I am currently using Diskpart to accomplish these functions, but i would like to be able to use P-Invoke and not have to shell out to an external process in my C# app.

The example Diskpart scripts are:

//Online a disk
Select disk 7
disk online

// Reset GPT Identifier
select disk 7
UNIQUEID DISK ID=baf784e7-6bbd-4cfb-aaac-e86c96e166ee

I tried searching pinvoke.net but could only find functions that dealt with volumes, not disks. Any idea on how to accomplish these diskpart commands using Pinvoke?

Answer 1

I'm not sure exactly what Dispart does but I'd suggest looking at WMI which might have this kind of functionality. It's usually a good place to look when you need to do something less common in Windows.

There's the Storage WMI Classes which might have something useful:

Edit: removed the suggestions about Volumes since I had missed that you're not interested in that.

Answer 2

How about the DeviceIOControl API?

If not, I would look into using WMI. In particular, take a look at the WMI WIN32_DiskDrive or WIN32_LogicalDisk classes.
