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 USB Device not recognized issue with Windows PC or any other device, where the USB port is not able to recognize the connected external drive. When you try to connect and access the data from external hard drive or 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- Windows have outdated driver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 are the solutions to fix External Hard Drive or USB Device not Recognized Error
Solution 1: Disconnect computer from power supply
Sometimes, very simple trick can fix unrecognized USB device problem. Follow below steps to apply this trick.

- Step 3: Now connect your USB device to the USB ports.
Solution 2: 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 3: Check for Driver Update
If all USB ports are working fine then you need to check for driver because sometimes old drivers can prevent the drive to connect to the computer and shows device malfunctioned message. To check driver status follow below steps.
- Step 1: Open Run dialog box by pressing windows + R key and then type devmgmt.msc and click on OK.
- Step 2: Expand Disk drivers and right click on the “connected external USB drive.” Click on “Update Driver Software”. Follow further instruction to update driver.

- Step 2: Select Disk Management.
- Step 3: Right click on the “connected external drive” and choose “Change Drive Letter and Paths.”
- Step 4: Click Add, and then assign a drive letter from the drop down list and click OK.
Solution 5: Fix the partition & file system
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.
- Step 1: Right-click inside the unallocated space and choose ‘New Simple Volume’ and follow the wizard to create a new partition.
- Step 2: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.
Note: As we know that creating new partition will overwrite the old data stored on the external USB drive. This leads to data loss. Therefore, before creating a new partition, you have to recover data from not recognize external USB Hard Drive.
