How to delete "Unknown Disk 3"
Windows is showing a Disk 3 that is not there. I'm not sure how it got there and I can't find a way to delete it.
Here is the screenshot from Disk Management

Really don't know what is happening and in the circumstances shoot all around in dark :)
1.Make sure you do not have any USB storage device connected to the front and rear ports. Sometimes a faulty pen drive can show up as an HDD..
2. Open Device Manager and check the disk drives shown. Also examine under USB for any unknown device.
3. No clues? Try Power cycling your PC. Remove all externally connected devices (except your Key board and mouse), shut down your PC and disconnect it from Mains pulling out the power plug. Leave it for about five minutes. Press the power button repeatedly a few times and hold for a few seconds to remove all charges in the PC. Power your PC now and boot.
Does your PC still show Disk 3 in WDM? Right click on Disk 3 icon on the left and check what Menu items you get and also check what it says when you try to initialise.

Hi Roland JS,
Click on the screenshot and you will get a full screen view of it with a zoom symbol. Click again and you will get a zoomed view.
If you still can't see anything, get your eyes tested ASAP.

Had the same thing last week on my machine and it claimed a "signature collision"?? meaning your disk 3 has the same signature with another drive in your system and therefore that drive is not recognized. My solution was to remove that disk, connect to another computer, rename it you have data on it or format it if you do not have data on it. Once I did that, then disk management tools was used to initialize & give it a drive # etc. YMMV

There is nothing currently connected except the keyboard and mouse and the 3 internal drives (SSD for Win 7, SSD for Win 8.1 and a hard drive for other things (mainly my recording studio project files - I also use the PC for my recording studio).
The only thing I can see is it was a USB attached drive at some point. The external USB attached drive I have works properly and shows up when I attach it, so its not that one.
I suspect it will have to be deleted in the Registry, but I don't know where it would show up.

Update, I just booted Win 8.1 (dual boot system) and Win 8.1 shows the exact same thing.
I checked the BIOS and the only thing listed is the actual drives that are connected (SATA connected).

Is there a reason why the system reserved partition is assigned Drive H: My DM looks like this: Windows thinks you have 4 disk's c:, D:, G:, and H:

That was the way the Win 7 Home Premium 64 bit installed from the OEM version disc. I installed on a clean drive when I built the PC 3 years ago.
