unknown "other devices"

Hi,

Unknown devices usually show up in the Device Manager when Windows is unable to identify a piece of hardware and attempts to provide a driver for it. An unknown device isn’t just unknown — it’s not functioning until you install the right driver. Most of
the time Windows is able to identify and download drivers automatically. In cases where it is unable to do so, you'll have to identify and look for the driver yourself.

Follow these steps to locate the Unknown Device:

1. Press Windows Key + X and select Device Manager.

2. You’ll find unknown devices and other non-functioning devices under Other devices. Each device with a problem has a little yellow exclamation mark over its icon.

To check the Hardware ID of a device, follow these steps:

1. Open the Device Manager.

2. In the Device Manager, right-click the device, and choose Properties in the popup menu.

3. Tap the Details tab.

4. Select the Hardware IDs in the drop-down list.

5. Search the web for the Hardware ID using your browser. You should be able to get the name of the piece of hardware associated with the unknown device.

6. Get the driver for the device and install it normally.

Windows 10: Unknown System (Z Partition or Disk.

Hi Leonardo,

There are several factors why you see unknown system partition or disk in your computer. It can be a recovery partition. For us to better assist you, we'd like to gather more information:

• What troubleshooting steps have you done so far?
• When did this issue occur?

Meanwhile, we suggest to follow these steps:

• Open a Command Prompt as admin.
• Type in diskpart.
• Type list volumes.
• Find out which volume shows as your drive E: then type select volume N, where N is the number that the volume was given.
• Double-check that you're on the right volume, type in "list volume" and check where the asterisk is. If it's beside the volume you wish to change, then good, if not you'll need to do "select volume N" again.
• When you're sure you're on the right volume, type in remove letter=E.
• Check it has been done by typing "list volume" to see the results.
• Close the command prompt window.
  

It will let you remove that partition.

identify unknown device

Go into DevMgr, open unknown device, click on properties, open the Details tab, then post the values you find in the Hardware IDs field. For example, for an OCX Vertex 3 drive on my system, here's what I get:



Let us know what you find when you do likewise. (Hint: you can search on this information in Google to identify devices yourself, too.)
HTH,
