If the Damage is Physical
Firstly, let us discuss whether the damage is physical or software-related. If it is some physical damage, then the only solution for repair might be a visit to a repair shop as software mechanics may not work for such a level of damage.
Another way of checking the physical damage is by inserting the flash drive in the other slot of your 1st Mac or in a 2nd computer. If your drive works this way, then your 1st computer slots are possibly damaged and need to be checked by a repairman otherwise the damage is most definitely related to software-linked issues.
If the Damage is Non-Physical
Another non-invasive technique to repair a non-functional USB Flash Drive is by updating the software of your Mac. Although macOS can update itself automatically but sometimes, a manual check-up might be needed to see whether there are some pending updates.
If the updates are available, then you will need to update your macOS which possibly will also install the available updates of USB Drivers. In case, this does not work, then one of the below-given advance recovery methods may be the only option that you can try before replacing your Flash Drive.
Methods to Repair Corrupted or Damaged USB Flash Drive on Mac
There are three ways in which you can try to repair your corrupted USB flash drive on Mac.
A Simple Reformat
The simplest method to try and give your flash drive another life is by reformatting it. But as you may have already realized, this will result in the loss of data that was present in the drive before it got corrupted.
After you are done with the reformatting, you can try one of the recovery software to retrieve the disk data but it is a better option to try recovery software before you go all-in for the reformatting process as the later process may have better chances of data recovery.
To perform a reset, connect the device to your Mac computer and launch Disk Utility. From the left panel, select your USB Device. Then, select Erase option from the top right side of the tab. Here, it is not recommended to select more Security Options for the sake of data recovery.
After that, give a name to your drive, and select the format type from the drop-down options to execute the format.
