USB flash drives, also known as pen drives and thumb drives, are great for exchanging photos with friends, transferring documents between computers, and backing up small files.
Perhaps because they are so versatile yet so fragile, many Mac users want to know how to perform flash drive data recovery. In this article, we describe several tried and tested solutions that you can use to recover data from any flash drive on Mac in no time.
How to Recover Files from a Flash Drive on Mac
It’s time for us to describe two solutions for data recovery from flash drives.
Solution 1: Check the Trash Folder
Recently deleted files can often be found in the Trash folder. If that’s the case in your situation, you’re in luck because flash drive recovery on Mac from the Trash folder is a very simple process.
To recover files from USB drive on Mac using Trash:
Step 1. Open Trash by clicking on its icon, located on the right side or bottom of the Dock.
Step 2. Go through Trash and look for the files you want to undelete. Select them by either pressing and holding the command key and then clicking the files or by holding the left mouse click and dragging the cursor around them.
Step 3. Click on any of the selected files, hold the click, and drag your mouse to another folder or your desktop.
Solution 2: Use USB Data Recovery Software for Mac
Permanently deleted files that can’t be restored from Trash can still, in most cases, be retrieved using special USB data recovery software for Mac. Such software analyzes the entire USB flash drive and looks for any recoverable data. Depending on which software solution you choose, you can expect it to recover as much as several hundred different file formats.
Disk Drill is easy-to-use data recovery software. It’s designed to recover files from USB on Mac with just a few clicks while delivering professional results. Disk Drill has a free preview feature for files so you can scan flash drive at no cost.

Common Reasons Why Files Disappear from Flash Drives
Let’s go over some of the most common reasons why files disappear from flash drives:
- 🧹 Accidental deletion or formatting: All it takes to delete important files from a flash drive is one wrong click. If you notice your mistake immediately, you should be able to retrieve your files from Trash, but files that are no longer in Trash can be recovered only with the help of Mac USB drive data recovery software.
- 🦠 Malware or virus: If your computer is infected with either malware or a virus, then it could be the cause of your Mac not being able to recognize or use a flash drive. When malware or viruses get bad enough, they can inhibit system speed, performance, and hardware connectivity.
- 💻 Improper ejection: It’s important that you always properly eject your flash drive before removing it from your Mac to avoid interrupting a write operation running in the background.
- 💾 Using the wrong flash drive: Some of us use multiple flash drives. Make sure that you’re using the right one when plugging it into your Mac if you’re not seeing your files you may have grabbed the wrong flash drive.
- 🔨 Hardware damage: If you use a USB drive with a damaged connector, you shouldn’t be surprised when you lose important files. To protect your files, keep your USB drive away from dust and water and, if possible, avoid carrying it loosely in your pocket with keys and spare change.
Why Can’t Some Files Be Recovered?
Unfortunately, data recovery is an unpredictable process, and you may not always be able to recover all lost files.
Generally speaking, files can be recovered until they are overwritten by new files. That can happen nearly instantly or after several months and even years—it all depends on the size of your USB drive and how much you use it. For example, if you accidentally format a 2 GB flash drive and write 2 GB of new files to it, it’s almost guaranteed that none of the original files will be recoverable.
Physical damage may also jeopardize the recovery of deleted files and even render the entire flash drive useless. Unfortunately, there’s not much regular home users can do to repair a physically damaged USB flash drive because any such repair requires specialized equipment and plenty of experience.
Another thing that complicates file recovery on some Macs is the lack of USB ports. For example, the latest MacBook Air offers just two Thunderbolt 3 (USB-C) ports and an audio jack—no full-size USB port available. Fortunately, all you need to recover files from a USB flash drive on a Mac that doesn’t have a full-size USB port is a suitable dongle.
How to Prevent Data Loss from USB Drive?
Preventing data loss from a USB drive doesn’t require any special skills or expensive software. You just need to treat your USB drive responsibly and keep in mind the following five tips:
- Use your USB drive responsibly: If you keep important files on your USB drive, you need to use it responsibly, which means properly ejecting it before you physically remove it from your computer and taking care not to interrupt any active read/write operations before they finish.
- Keep your USB drive away from dust and moisture: Physical damage can wreck a USB drive in an instant, and it’s often impossible to repair it. To prevent it, keep your USB drive away from dust and moisture and always use the included cap to protect the USB connector.
- Back up your files from time to time: Just because most people use USB sticks as cheap and handy backup devices doesn’t mean that you shouldn’t back up your files from time to time. It’s always much better to lose a day’s or a week’s worth of work than everything.
- Defend your computer against malware: Malicious hackers love USB sticks because they make it easy for them to spread their malware from one computer to another. To prevent your USB stick from becoming a host for a virus or some other digital parasite, use a reliable anti-malware solution.
- Don’t rely too much on a single USB drive: Considering how affordable USB drives are, there’s no reason to rely on a single and risk losing gigabytes of data at once. Instead, buy multiple USB drives and use each for a different purpose. That way, even if one of them stops working, the data loss won’t be terrible.
With these five tips, you can prevent data loss from a USB drive and avoid the loss of time and valuable data associated with it. But even if you do lose important files, remember that you can always recover them using USB recovery software.
