USB stick does not register when inserted into USB drive

[AT-5_BH]

I have a USB stick that has stopped registering when put into my USB drive on my computer.  How can I get my USB drive to identify my USB stick so that I can view the files that I know are still on it?

Hi @AT-5_BH,

Welcome to the HP Support Community.

I understand that the USB stick previously worked, but the HP Slim Desktop PC S01-pF2000i no longer detects it. Since the stick contains important files, please do not format or initialize it.

First, please confirm:

• Does the USB stick work on another computer?
• Do other USB devices work in the same USB port?
• Does the stick work in another port on the HP desktop?

Next, open Device Manager and check Disk drives and Universal Serial Bus controllers. If the stick appears as an Unknown USB Device, right-click it, select Uninstall device, and restart the computer.

Also open Disk Management. If the USB stick appears there without a drive letter, right-click its partition and assign an unused drive letter. Do not select Format or Initialize.

To test the computer’s USB hardware:

1. Restart the computer and repeatedly press Esc.
2. Press F2 to open HP PC Hardware Diagnostics UEFI.
3. Select Component Tests and run the available USB Port test.

Please share what happens when the stick is tested on another computer and whether it appears in Device Manager or Disk Management.

Take care and have an amazing day!
