Question Laptop not detecting external HDD ?

Sep 14, 2015
Hiya. Could use a hand from people a little more tech savvy than me.
One moment an external SATA hard drive connected via USB is working fine, and then the next it disappears from File Explorer. Reconnecting it, trying different USB ports, and going through Windows Update didn't seem to do the trick.

I tried finding it through Disk Management, no luck there either.
This exact set of problems persist with a second external hard drive.
I can't find any faulty drivers on Device Manager, and uninstalling a SATA driver didn't work either.
Has anyone experienced this before or have a clue of what the problem might be?
  1. Press "Windows + R" keys.
  2. Type "control" and press enter to open the control panel.
  3. Type "troubleshooting" in the control panel search box and open it.
  4. Click "view all" on the left pane.
  5. Run the hardware and devices troubleshooter and follow the on-screen instructions.
See if this helps at all.
