How to retrieve files from a corrupted USB drive?

I was transferring files to my MacBook Air using my new USB flash drive, I got distracted by a conversation in the room and absentmindedly pulled it out without safely ejecting it first. Now my flash drive is empty of files I had put into it. I really need those files. Is there a way to retrieve it? Could it possibly be somewhere on my Mac? I think the flash drive is corrupted because I had given the flash drive a name and now when I plug it in, it has a corrupted-looking name with different symbols. PLEASE HELP ME!

First, check if the files are transferred to your MacBook Air successfully. If you can't find them on your Mac, it means the files haven't been moved successfully from your USB flash drive. The reason why your USB flash drive is empty now is that the USB drive gets corrupted due to unsafe ejection.

To repair a corrupted USB drive on Mac, you can use Disk Utility.

  1. Open Disk Utility from Finder > Applications > Utilities.
  2. Connect the USB to your Mac, and click View > Show All Devices in Disk Utility.
  3. Select the USB drive from the left device list and click First Aid.

If the Disk Utility failed to fix the corrupted flash drive, then your USB drive may get damaged severely, you'd better replace it or reformat it to use. However, reformat will wipe all data on it. Since these files are very important to you, you can use professional data recovery software to retrieve them first before reformatting it.
