External USB drives (Hard Drive, Pen Drive, Memory Card etc.) are the simplest way to transfer the stored data from one device to another. Usually, these USB drives are easy to handle, but sometimes, you might face connection issue with Windows PC or any other device, where the USB port is not able to recognise the connected external drive. When you try to connect and access the data from any external USB drive, you see the following error message:
“One of the USB device attached to this computer has malfunctioned, and Windows does not recognize it. for assistance in solving this problem, click this message.”
This error/issue can be caused by following situations:
- Windows have outdated driver
- Dead USB ports
- Partition issues on your external USB drive
- Wrong file system
- Virus infected PC
- Dead USB drive itself.
You can follow below solutions to resolve the above-explained problem applied for both USB flash drives and larger external hard drives. Here is the solution to fix an External Hard Drive not recognised/detected ?
Solution 1: Check for Dead USB Port
Unplug the drive from the current USB port and try to connect the drive to another USB port on your computer. If it works then, you might have a dead USB port. Or if you are using a USB hub, then try to connect the drive directly to the computer instead of as some USB hubs don’t provide enough power to run the external drive. If the USB port is working and still you face the same problem then try another solution.
Solution 2: Check for Driver Update
First, determine whether Windows detects the external hard disk drive when it’s plugged into the USB port. Connect you targeted drive to your system, at times some of the external hard drives need to switch on to get activated. Moreover, some removable hard drives might have to be plugged in with some separate power cable to get access.
- Now, open the Disk Management, where you will be able to see all the connected external drive listed under the Disk Management window. This list includes all the connected drive, even those drives that are not appearing in your Computer window due to partition issues.
- If your connected drive is listed here, you need to format it correctly so that your system or other devices can recognise and access it.
- In case, your drive is not showing in Disk Management window then, continue to the next section to make your drive visible.
Making External Hard Disk Visible in Disk Management
If the Windows does not recognise the external hard drive, then possibly your computer has a faulty USB port, an outdated driver, or above all you might have a dead drive.
Follow the steps to determine why External Hard Disk Drive not recognized:
Check the USB port
- Unplug the drive from the current USB port and try to connect the drive to another USB port on your computer. If it works then, you might have a dead USB port. Or if you are using a USB hub, then try to connect the drive directly to the computer instead of as some USB hubs don’t provide enough power to run the external drive.
- If still the drive doesn’t appear in the Disk Management even after skipping the USB hub and connects it directly to another USB port, then either your drive itself is bad, or the computer is having a problem. To clarify this confusion, you need to check your hard drive is detecting or not. You can try it by connecting to different system/port.
- If still, it doesn’t work, then also check whether it appears in that computer’s Disk Management window, if not then possibly your drive itself is faulty and need to be replaced.
Update or un-installed Driver
- If the external hard drive does work on another computer then possibly your Windows has a driver problem. Check for the driver using Device Manager.
- Go to under Disk drives and check the driver for all the devices next to them. If a yellow exclamation mark is there, then you have a driver problem. To update the drive right-click the device with a yellow exclamation mark, go to Properties, and check the error message. This message can surely help you fix the problem.
- If you are unable to understand and fix the problem, then you might use Google to search the problem. In case the problem started recently, you can also use System Restore or install an updated driver using the Update Driver button. To revert any changes use the Roll Back Driver button or uninstall the device from your system using Uninstall button.
Partitioning or Formatting issues with the Drive
- Windows Disk Management tool is used to fix the partition & file system related issues. If the drive has a partition issue and is full of “unallocated space,” then you need to create a new partition on it. You can do this using Windows operating system.
- To initiate this, right-click inside the unallocated space and choose ‘New Simple Volume’ and follow the wizard to create a new partition.
- If you have partitioned your hard drive properly but still not able to show, then make sure you have assigned a drive letter to access it on Windows. Usually, this happens automatically, but at times you need to do it manually when the drive does not show up in Windows with a drive letter.
- To create a new drive letter right-click on the removable disk’s partition, choose ‘Change Drive Letter and Paths’ and add a drive letter.
- You need to format the hard drive as NTFS if you are unable to access the Hard Drive. Some devices can’t read the NTFS file system as they only follow FAT32 file system. To fix this problem, simply reformat the NTFS partition as FAT32.
If the process mentioned above resolves most of the disk recognition issues, but still the problem persists “Hard disk drive not recognised” by any computer, then it’s probably dead. Then you need to use a External Hard Drive Recovery Services to procure the stored data from the External hard disk.
