How to Fix Unreadable and Corrupted External Hard Disk


How to Fix Unreadable and Corrupted External Hard Disk – A system error can cause an unreadable external hard disk on your computer or laptop device. However, not a few of us do not know how to solve an unreadable Hard Disk.

What is a Hard Disk?

A hard disk is one of the computer hardware (hardware) that provides storage space that can be used to store or read data on the computer. Hard Disk is a type of computer memory with non-volatile memory properties, which means that data in this type of memory will not be lost even if the device is turned off. Unlike the RAM storage media, which only stores data as long as the device has power.

Hard Disk Function

Hard Disk is a large-capacity memory on a computer that serves to store or read data on the computer. The stored data includes your operating system (Windows, Linux), software (browser, office, etc.), as well as your data (documents, photos, songs, etc.).

Hard disks have various capacities that can store up to billions of bytes. Usually, the larger the size of the capacity of a Hard Disk, the lower the RPM speed (rotates per minute).

RPM here refers to the rotational speed in one minute carried out by one of the components of the Hard Disk called the platter. Each Hard Disk has a different rotating speed depending on the type of Hard Disk, but the widely used speed is 5,400 rpm.

Then what if the external hard disk cannot be read? The following is how to fix an external Hard Disk not reading on Windows and Mac OS.


How to Fix Unreadable External Hard Disk

1. Connect to Another USB Port

The first way to solve the external Hard Disk not being read in Windows 10 is to connect the USB Hard Disk cable to another USB port. If previously connected to a USB 3.0 port, it can be moved to a USB 2.0 port. When you are using a computer, you can try reconnecting the USB Hard Disk to the USB slot behind the CPU.

If it doesn’t work to connect to a device with a Windows system, you can try connecting the Hard Disk to a Mac device. There is a possibility that the Hard Disk you are using is not formatted for the Windows system.

2. Update Hard Disk Drivers

There are times when Windows encounters driver issues that make devices such as external Hard Disks unreadable and beeping. To overcome this, you can do something like this to solve it:

  • Click Start, then open the ‘Device Manager’ by typing it in the search feature.
  • If you see the Hard Disk has a yellow exclamation mark, then right-click on the Hard Disk and select ‘Properties.’
  • Later, you will get some error codes.
  • After that, select the ‘Driver’ tab and ‘Update Driver.’
  • Perform the Restart process to resolve an unreadable Hard Disk.

3. Clean Hard Disk

The Hard Disk will appear in ‘Disk Management,’ but the drive will not work in some more specific cases. You can clean the Hard Disk to solve this. But keep in mind, by doing this, all data on the Hard Disk will be erased. Here’s how to clean the Hard Disk partition:

  • Click ‘Start’ or the ‘Windows’ icon in the lower-left corner.
  • Type ‘diskpart’, then press Enter.
  • When the prompt window appears, type ‘list disk’ and press Enter to view the connected devices on the system.
  • If you see a Hard Disk device, note or remember the name of the Hard Disk (e.g., Disk 2).
  • After that, enter the command ‘select disk 2’ and press Enter.
  • Finally, enter the command ‘clean’ and press Enter.

4. Enable and Format Hard Disk in Disk Management

If your Hard Disk is turned on, but it still doesn’t appear in File Explorer, then you can find out why the external Hard Disk is not reading in the following way:

  • Click Start, then type ‘Disk Management.’
  • Press Enter when the ‘Create and Format Hard Disk Partitions’ option appears.
  • Once ‘Disk Management’ opens, scroll down and find your Hard Disk in the list.
  • If you have found it, right-click and select ‘Online.’
  • Next, make sure the Hard Disk is formatted. If it has not been formatted, the Hard Disk will display the word ‘Unallocated.’
  • If it has not been formatted, right-click on the Hard Disk and select ‘New Simple Volume.’ Keep in mind that this format process will erase all data on the Hard Disk.
  • You can right-click and select ‘Change Drive Letter and Paths if it doesn’t work.’
