How to Recover Files Disappeared From Flash Drive
After connecting your USB drive to your computer, were you surprised to find that some of your files have disappeared? Most people would be. It’s hard to believe that your files could have just up and vanished. Well, unfortunately, it can happen.
The good news is that you can usually get your files back. In this article, we’ll look at why this happens, as well as how to recover files that disappeared from your USB flash drive.
Why Do Files Disappear From USB Drives?
There’s no single reason why your files may have disappeared from your USB flash drive. Before you try and find the files missing on your flash drive, it’s important to understand why they may have disappeared so you can prevent other files from also becoming lost.
🗑️ Accidental deletion
Accidents happen. A simple misclick can result in some or all of your data becoming deleted. Even formatting can happen by mistake. In these cases, we recommend recovering your data right away.
🦠 Virus infection
Malware, like viruses, can infect your USB flash drive and either hide or delete your files. Remove any viruses first, then show hidden files. If they’re deleted, perform data recovery.
⚠️ File system corruption
A broken file system prevents your operating system from finding your data. It can happen as a result of physical or logical damage, such as improper ejection. You can recover the data first, then try fixing the flash drive.
💥 Physical damage
Physical damage is the worst kind. It can occur from the USB drive being dropped, crushed, or thrown. You can try data recovery yourself, but if the USB isn’t being detected or reading the correct size, using a data recovery service is your best bet.
⏏️ Improper ejection
Removing a USB flash drive before ejecting it safely can interrupt processes, corrupting the data and file system. Recover your data immediately, then perform a quick format to fix the USB.
🖊️ Accidental overwriting
Overwritten files cannot be recovered using data recovery software. Instead, you should restore the files from a backup or restore them to a previous version using File History.
❌ Fake USB
Scammers often sell USB drives and claim they have a higher capacity than they actually do. These USB drives are modified so they look legit when you plug them in, but when you write large amounts of data that exceed their actual capacity, the files disappear or become corrupted. You can check this using Fake Flash Test.
Methods for Recovering Files That Have Disappeared From a Flash Drive
There are lots of methods available for recovering files that have disappeared from your USB flash drive. We recommend you start with the first method and work your way along to ensure you’re not missing any important steps.
method_1: Use a Recovery Tool to Restore Disappeared Files

We at Pandora Recovery have made it our goal to ensure you have the best chance of recovering your data. To achieve this, we scour the web for all the data recovery tools we can find and put them through a meticulous multi-day testing process to discover each tool’s strengths and weaknesses. We can then pass on the results to you, our readers.
The outcome of our testing shows us that Disk Drill is the ideal data recovery tool for restoring files that disappeared from your USB. Here’s why:

If some of your files have disappeared and no longer show up on your USB flash drive, using a data recovery tool is essential. This is how you can recover files that have disappeared from your USB flash drive on Windows 10 and 11 using Disk Drill:
- Download and install Disk Drill.
- Connect your USB and select it from the device list. Click Search for lost data to begin the scan.
- Click Review found items to explore what Disk Drill discovered. Alternatively, click the colored file type icons to filter the results immediately, or just recover everything by clicking Recover all.
- Select the disappeared USB files that you want to recover. Be mindful of the recovery chances column, as it will show you what files can and cannot be recovered. When you’re ready, click Recover.
- Select a suitable recovery location. Make sure you don’t recover the files to the same USB you’re restoring them from. When ready, click Next to complete recovery.
method_2: Reconnect the Flash Drive to Your PC
An unstable connection can cause issues with your computer reading your USB flash drive. Try ejecting your USB safely and then reconnecting it. Use a USB port that connects to your motherboard directly (on the backside of most computers), as the cable connecting your computer case’s USB ports to your motherboard may be faulty.
method_3: Scan the USB Drive With Antivirus Software
If your files are not showing up on your pen drive, it may due to a virus that has hidden or deleted them. Before you attempt to unhide or recover them, make sure you remove the virus first. You can do this using Microsoft Defender Antivirus which comes with Windows 10 and 11 by default.
- Open File Explorer and shift-right-click your USB drive. Click Scan with Microsoft Defender. This will begin a quick scan.
- To perform a more extensive scan, select Microsoft Defender Antivirus (offline scan) and click Scan now.
method_4: Unhide Hidden Files & Folders
Are your USB files missing but the space is still used when you check File Explorer or Disk Management? There’s a chance they’re just hidden. The ‘hidden’ attribute can be applied to files so they won’t appear like normal. You can show hidden files to unhide these files, then manually remove the ‘hidden’ attribute.
- Open File Explorer.
- Navigate to your USB drive. Click View, Show, then Hidden items.
- Select all the hidden data and click Properties.
- Untick Hidden and click Apply.
method_5: Fix Flash Drive Errors Using Command Prompt
CheckDisk is a wondrous repair tool. It’s used to scan for and fix logical and physical errors relating to your file system and file system metadata. When files copied to a USB drive disappear due to some form of damage, try repairing the damage using CheckDisk. You can access it using CMD.
- Right-click Start and click Terminal (Admin).
- Type chkdsk *: /r. Replace * with the drive letter of your USB drive. Press Enter.
method_6: Perform a Quick Format of the USB Stick
You may be thinking a quick format is counterintuitive considering it deletes the data on the USB stick in the process. But, quick formatting is a very effective way of fixing various issues that could have caused your files to disappear. In cases like this, we recommend you follow the steps from method_1 to recover your data first, then proceed with the steps below to quick format the USB flash drive.
- Right-click Start and click Disk Management.
- Right-click the USB’s volume and click Format.
