External hard disk Not readable

9-1-1 Was ist Ihr Notfall?

"USB drive not recognized!"

There are many causes that can cause your USB hard drive to not be recognized.   The reason for "hard drive not being recognized" could simply be a loose cable or your hard drive has actually failed. 

We would like to show you here in a simplified way how you can access your data and save a lot of time. But the main point is to save your data.

Disk management

Problem: The disk structure is damaged and not readable! 

The first thing to do is to determine whether the hard disk is sighted in the Disk Management.

Proceed as follows: 

  • Click "Start".
  • When the "Start Directory" opens, right click on "Computer 
  • Select "Administration".
  • Now the "Computer Management" window should open
  • Select "Disk Management". 

Now you should be able to determine if the hard disk is being viewed by the computer by looking at the name of the hard disk followed by a letter (E:).

If you see the hard disk but no letter like E: or F:, your computer has lost the structure.

  • You should then right-click the external hard drive, 
  • then click on "Change drive letters and paths
  • then click on "Add
  • then click on "Assign the following drive letters
  • then choose a letter for your drive 
  • then click on "OK 


Now your drive should be recognized by the computer.   If the renamed drive is not visible, go to "Cables and external enclosures".

Cables and External Enclosures

External hard drives are designed to transport data from one computer to another.   However, after a certain period of time, the cables or connections may become damaged.   If you are faced with a computer problem, look for the closest thing - the cable.

  • Take a USB cable (or borrow one from a friend) and connect it to the external hard drive. 
  • Remove the hard drive from its original enclosure and connect it directly to the computer with a SATA or IDE connection

 If the hard drive is detected, the problem was with the USB cable or external enclosure.

Your data is in danger!
