  1. The hard disk may no longer be recognized by the disk management utility in windows may be because of an invalid partition table.
  2. For many external hard drives, an incompatible/malfunctioning USB cable will, on occasion, introduce this error.
  3. Major performance problems as a result of factors such as bad sectors or corrupted files can also give rise to the snag.
  4. Mechanical damage suffered after an accidental fall or from mishandling
  5. Firmware and malware mishaps.

  2. Swap the USB ports

1. Restart everything

  1. Shut down the PC.
  2. Turn off the external hard disk (the types that use a separate power cord).
  3. Turn your PC back on.
  4. Switch the hard disk back on.

It may sound simplistic but restarting the entire systems does help in some instances. The annoying message may go.


2. Swap the USB ports

Sometimes USB hard disks receive insufficient power from some USB ports, or have functional issues with certain ports. USB hubs are particularly susceptible to this.

Furthermore, sometimes the ports on the PC may serve differently, so trying a couple of different ports can be beneficial.

So, disconnect the disk from the current USB port and connect it directly on one port on your computer (not on the hub).


3. Check the Device Manager for hard drive issues

  1. Press and hold down (or right-click) on the Start button.
  2. Select Device Manager on the context menu.
  3. Locate any device with an exclamation mark next to it (or other peculiar issues).seagate fatal error device discovery

(This will require the hard drive to be reinstalled before any fresh attempt to access the contents).

  • One-year limited warranty
  • Quite noisy

  1. Unplug the disk.

  3. Select Action then Rescan Disks (when prompted).

Sometimes the error disappears after the hard disk has been rescanned for errors.


8. Ensure that the drive is receiving power

For external Desktop hard drives, plugging the power cable directly into the wall outlet (instead of the UPS-universal power supply or a power-strip stabilizes the power supply).

For portable drives, using a USB power booster cable can help supply extra power.

  2. Right-click on Command Prompt (Admin) from the menu list.
  3. Type cd\ and press Enter.
