How to Recover Deleted Data from a USB Flash Drive on Mac

Without a doubt, USB drives are incredibly convenient devices for data storage or transferring files between computers. But just like any other storage device, they’re not flawless. There’s always a tiny chance that something may go wrong, and you’ll lose a valuable file.

So what should you do if a file that you’ve uploaded to the USB drive mysteriously disappeared? How to recover data from a flash drive on Mac? Read on to find the answers.

Why Files Disappear From USB Drives

Knowing why files can disappear from flash drives may help you recover your lost files. So before we get to the main part, let’s go through the main reasons why data can get lost on a USB drive:

Is it Possible to Recover Lost Files from USB Drive on Mac?

In most cases, yes. Thanks to modern data recovery solutions, you’ll be able to recover most, if not all, deleted files from your USB drive in a few simple settings. This applies to data loss scenarios like minor corruption, an interrupted move operation, or an accidentally formatted pen drive.

But, it’s imperative to act quickly and avoid writing new files to the drive before recovering your data.

If the USB drive is physically damaged or severely corrupted, DIY data recovery is usually not possible. In these cases, stop using the drive immediately, and contact a professional data recovery service to get back your data.

How to Recover Files From USB on Mac

The first thing that you should do is stop using the USB drive. Just keep it disconnected from your computer until you are ready to start the flash drive data recovery on Mac.

It’s impossible to stress enough the importance of doing this since it’ll prevent the possibility of data overwriting and, therefore, will help with recovering your files.

Method 1:Use Data Recovery Software

Now let’s start the USB data recovery on Mac. The most reliable and effective method of restoring USB on Mac is by using a data recovery tool.

Disk Drill is a great example of such an application since it’s simple to navigate and is pretty versatile. Moreover, it supports all types of USB devices and can recover almost any file (images, videos, documents, archives, and more).

Here’s how to recover a USB drive on Mac using Disk Drill:

1. Download and install Disk Drill if you haven’t already. Click the file and follow the onscreen instructions to finish the installation.
2. Connect your USB drive to your Mac and launch Disk Drill. From the list of storage devices, choose the connected flash drive.
3. Click the Search for lost data button located on the bottom-right of the screen to start scanning your device.
4. Click Review found items to preview the files while the application is scanning your drive or wait for it to finish the scan.
5. Once you’ve found the needed files, click the box near that file to choose it. If you want to recover all of the files, click the box at the top of the files list. When ready, click Recover.
6. A pop-up window will appear asking you to choose a folder where you want to keep the recovered file. Click the needed location and click Next.

Note: The free Disk Drill for Mac version doesn’t allow you to recover the files from a USB drive but only to preview them. So if the scan has revealed the needed file and you want to proceed with the recovery, you should get the pro version.

Method 2:Recover Recently Deleted Files from Trash

When you delete a file from your USB drive, it doesn’t disappear for good right away — it gets moved into the Trash folder first. So if not much time has passed since you’ve manually deleted a file from your flash drive, the chances are it can still be found in Trash on your Mac and easily recovered.

Important: If you’ve already emptied Trash after deleting the file from your flash drive, then this method won’t work in your situation. The only solution will be to use a Mac USB recovery tool to restore the file.

Here’s how to recover files from a USB on Mac via Trash (if you’ve just recently deleted them):

1. Launch Trash on your Mac. It is usually located on the right side of the Dock.
2. Look through the files located there.
3. Once you find the lost file from your flash drive, drag and drop it into a different folder or back into the USB drive.

Method 3:Unhide Files on the USB Drive

In order to avert unintended changes and deletions, macOS can hide certain folders on the USB drive. Typically, these folders contain app settings, deleted files, and other data. It’s possible that the files you’re looking to recover have simply been hidden by macOS.

Here’s how to unhide these files:

1. Connect the USB drive to your Mac.
2. Navigate to the USB drive in Finder.
3. Press Command + Shift + . (dot) to unhide hidden files. You can use the same shortcut to hide the files again.
4. You can look in the .Trashes folder to view any files that were deleted from the USB drive.

How to Fix a Corrupted USB Drive

If data disappeared from your flash drive without your interference, it’s possible that the USB drive is corrupted. In such a case, before you start using it again, it is best to fix the issue.

There are two ways to fix a corrupted USB drive on your Mac: via Disk Utility or by formatting it.

Solution 1:Run First Aid

Disk Utility has a feature called First Aid that can fix errors of any storage device on Mac. So if your USB drive isn’t working properly, you should try to fix it with First Aid. If this doesn’t help, then the last option that you have left is to format the device.

Here’s how to fix a corrupted flash drive on your Mac via Disk Utility:

1. Head to Launchpad and click Disk Utility to open it.
2. Look through the list of devices on the sidebar. Click your USB drive to select it.
3. Click First Aid at the top.
4. Click Run to confirm.
5. Wait for the First Aid process to finish. Click Done.

Solution 2:Format the USB Drive

You should also use Disk Utility to format your flash drive on Mac. Make sure that there are no files located on the device before formatting it since after the process is finished, all of the data will get erased from the USB drive.

Here’s how to format a USB flash drive on your Mac via Disk Utility:

1. Head to Launchpad and click Disk Utility to open it.
2. Click your USB drive from the list of devices on the left side of your screen.
   Click the Erase button at the top.
3. Type in a name for your flash drive in the Name field. If you plan to continue using the drive with your Mac, choose the Mac OS Extended (Journaled) format or any other suitable format.
4. Click Erase.
5. Once the USB Drive is formatted, click Done and eject your device.

Now you’ll get a fresh start with your flash drive. You can start uploading files to it and using the USB drive as desired.
