Applies to: Fix an external hard drive not detected due to a connection problem.
If you encounter problems with an external drive suddenly not working or becoming undetectable to your PC, the first thing to check is the physical connection.
#1. Check and Change External Hard Drive Connection Cable
Start off by checking the connecting cable between your drive and PC:
- If the USB connector has become loose in the port, just push it firmly back into place and see if that corrects the problem.
- If the cable is broken or damaged, replace it with a new one and try again. In fact, even if you can’t see any obvious damage, it's worth swapping the cable in case there is a problem inside.
#2. Change a USB Port or Connect to a New Computer
If the cable appears fine, then it could be the USB port on your PC that's faulty.
Try plugging the drive into another one to see if that helps. If possible, you can also try connecting the drive to a different computer to see whether the problem is with the drive or PC.
#3. Check Power Management for USB Hub
If none of the above methods get the drive working again, you should check to see if the power management settings in Windows could be causing the issue. Here's what to do:
Step 1. In Run (Windows + R), type devmgmt.msc and hit Enter.
Step 2. Open Device Manager > expand "Universal Serial Bus controllers".
Step 3. Right-click USB Root Hub > Properties > Power Management > uncheck "Allow the computer to turn off this device to save power".
- If your external hard drive is physically damaged, you’ll need to take it to a maintenance center for repair.
After following the tips above, hopefully, your computer should be able to detect and recognize your external hard drive. If that’s the case, you can try to open the drive and access the data.
If that’s not possible, don't worry. Move to Part 2 and we'll show you how to use the hard disk data recovery software to restore all your precious data.
After making the external hard drive detectable, we suggest that you recover any data stored on it immediately. This will not only ensure you have a copy of the files but also avoid the possibility of losing anything stored on the disk while trying the fix the problem. Here's how to salvage your files with a free file recovery program.

Method 1. Check and Fix Disk Errors on External Hard Drive
Applies to: Fix external hard drive that's not working due to unknown disk error or corrupted file system.
Mostly, when an internal or external hard drive contains an unknown error or a corrupted file system, the Windows PC will be unable to detect or open the drive.
Here are two options you can try to fix these problems.
Option 1. Run Partition Manager Freeware to Fix External Hard Drive Not Responding Error

Step 1. Right-click the target partition that has a problem.
Step 2. Choose "Advanced" > "Check File System".
Step 3. In the Check File System window, check the "Try to fix errors if found" option.
Step 4. Click "Start" to check errors on your partition.
Option 2. Run CMD to Manually Fix External Hard Drive Errors
- Running chkdsk can hopefully fix the external hard drive errors, however, it can also result in total data loss. So, perform data recovery in advance, and then continue with the CMD method.
Step 1. Type cmd in the Search box, right-click to open Command Prompt.
Step 2. Right-click "Command Prompt" and choose "Run as administrator".

Step 1. In Run (Windows + R), type diskmgmt.msc and hit Enter.
Step 2. Go to Disk Management, right-click the external hard drive, and select "Format".

When this is done, your external drive should be safe to use once more
Method 3. Create A New Partition in External Hard Drive
Applies to: Fix disk displays as unallocated in Disk Management that makes external hard drive not working.
Mostly, when your external hard disk shows as unallocated, it means that there is no partition in the disk. As a result, the computer cannot recognize it. To fix this issue, you need to first recover data from the disk first (as shown in Part 2).
Then, you can follow the steps below to create a new partition, making the external hard drive working again:
Step 1. Connect the unallocated external hard drive to your PC and open Disk Management.
Step 2. Right-click on the unallocated space of the external hard drive, select "New Simple Volume".
Step 3. Set partition size, drive letter and file system (NTFS), etc.
Step 4. Click "Finish" to complete the process.
Method 4. Assign a New Drive Letter to External Disk
Applies to: Fix disk shows as "New Volume" with no drive letter that causes external hard drive not responding.
Step 1. Go to Disk Management and right-click on your external hard drive.
Step 2. Go and select a new drive letter by clicking "Change", and click "OK" to confirm.
The non-responding drive should now be readable by Windows.
Method 5. Initialize External Disk and Create a New Volume

Step 1. Right-click "My Computer" > "Manage" to run Disk Management.
Step 2. Here, right-click the Unknow external hard drive and click "Initialize Disk".
Step 3. Select the disk(s) to initialize and choose MBR or GPT partition style, then, click "OK" to confirm.
Now the drive should be recognized as ‘unallocated’, so if you have data you need to recover, go back to Part 1 and use the EaseUS data recovery software to retrieve your files.
Step 4. Finally, right-click on the unallocated space on your external hard drive and create a new volume on it.
Method 6. Update Disk Driver
Applies to: Get non-responding external hard drive to show up and work by updating disk drivers.
Step 1. Right-click "This PC" and choose "Manage".
Step 2. Click "Device Manager" then expand "Disk drives".
Step 3. Find and right-click the problematic external drive and select "Update driver".
Step 4. Click "automatically search for driver software online".

Sometimes, the problem causing your drive to malfunction can be a virus or malware on your system. If you’ve tried the methods outlined above without success, another option is antivirus software. Here’s how to use it:
Step 1. Install and run antivirus software on your computer.
Step 2. Scan and unlock the external hard drive.
Step 3. Wait for the cleaning process to complete, then, restart the PC.
After this, reconnect your external hard drive to the computer and check if you can use it again.
