Windows 7: How to delete "Unknown Disk 3"

At this point and based on the new information provided by fireberd that he is using the Roland Capture device both on Windows 7 and 8.1, I am inclined to think that that program/device is creating a virtual drive for its operation. Anyway let me wait and see what comes out of ComputerGeek's investigation.

Fireberd did say that he uninstalled the driver for the unknown device. Perhaps we should have asked him to check the driver details and wherefrom those drivers emanated. It may not be the generic Windows drivers but device specific driver installed by the device that could give a clue to the device.

tip:
  • All disk drives use the generic MS driver. (It's become standard)
  • Every driver has a .inf file. The inf file for Microsoft's generic disk driver is disk.inf
  • Other clues Fireberd's device is just another generic disk. Look at the registry data Fireberd provided
    • You'll see disk.inf mentioned in several spots among the registry data
    • If you use DevMgr to look at any disk on your machine, you'll see they all have the same Driver key
      Code:
      {4d36e967-e325-11ce-bfc1-08002be10318}
      (The top snapshot below is my Crucial SSD disk) That specific GUID is reserved for the generic MS disk driver. Firebird's registry data shows that same GUID as the driver GUID for his mysterious device
    • It's only the numbers between {} that indicates the driver GUID. The \nnnnn that follow, where nnnn is a different numeric for each device, is a reference to the GUID per device that's using that driver.

/* EDIT */
So the device driver wouldn't help (as it's generic). One needs to figure out the parent devices to try and figure where it's coming from

What I was thinking aloud was something like this:

How to delete "Unknown Disk 3"-16-03-2015-21-37-19.jpg

Here it is a virtual CDROM drive. Examining each driver file gives the Provider's name, File version etc., etc.,

In Fireberd's case, do you think Driver File Details for that unknown USB device which in reality seems to be associated with some program/device, is not going to yield some information on the Provider? Or is it going to be only Microsoft as the provider?

May be Fireberd will be the best person to examine and tell us.

Ahhh.. Gotcha. Yep. Is certainly worth to check

Its just the stock Microsoft driver. Its identical to the three other installed drives.
I posted a screenshot of the Registry listing for this device. I considered deleting the registry entries for this device to see what happens, but the registry won't let me delete it. The Roland Studio-Capture is not the problem. I have the driver for this installed on a Laptop (for on-site recordings) and the USB device does not show up on that system.

Firebird: again, the info i really want to see is the full DevManView report (saved as Tab Delimited Text) Please run it for me so I can have a look

Your snapshots keep showing DevMgr in default view. Have you changed the view and looked for USB Device? (Along the top of DevMgr click View->Device by connection.) It's very possible USB Device will NOT be found under a USB Controller (but still have a look there to double-chec). So expand all the devices and search for it as best as best you can.

It may not be listed under PCI bus either (if it's virtual), so try a look through all the categories displayed.
Thanks

/* EDIT */
You don't want to delete it from the registry. Uninstalling the device as you once did will remove that device entry from registry. HOWEVER, based on your prior post, Windows will still detect it's (probably virtual) presence and re-enumerate it again (re installing those registry entries again). So simply deleting that entry is not the solution IMO

What I'm showing from the Device manager IS the device. Its not a hidden device. What I posted from the DevManView report IS the device. What I listed from the Registry IS the device, linked from the DevManView report. The only unknown is where its coming from.

I can post the full report, but the device has been located and listed.

You're a seasoned member of this forum. When you ask for a report - do you want the OP to provide the report or have the OP simply tell you the only things they think matter and you never get to see the actual report, itself

What else can I say? I shouldn't have to explain everything data item I look for and why its important to get an answer. And I don't guarantee I'll even see anything else. You're most welcome to add your own take on the data but I still need to see info i request.

If you want my help, please provide the information as requested. Otherwise, I'm sure the others will be happy to continue to provide you help

I've given you all the information. Nothing else to give you but you want more so I closed the thread.

This is my recording studio production system. The device does not interfere with recording operations so I'll leave it as is.
