You have a few options if you discover that you have deleted important files from a USB or flash drive. The files might be in your Trash bin. If you are in the practice of backing up your USB drive, that presents another way to potentially recover your files. If those methods are not available to you, you need to rely on data recovery software to restore your valuable data.
Disk Drill Data Recovery Software
Disk Drill is an excellent data recovery utility that can restore deleted files from your Mac’s internal and external storage. This includes USB and flash drives. The software employs advanced scanning algorithms that interrogate the USB drive sector-by-sector to salvage and recover files in hundreds of different formats.

Preventing Data Loss on USB Devices
Two of the most appealing characteristics of USB drives are their size and portability. They are an excellent choice for exchanging files with friends or colleagues. You can use a USB drive to add extra storage capacity to your machine or to segregate specific data. Using a collection of USB drives to store creative projects makes it easy to transport them and saves storage space on your internal drive.
The convenience afforded by USB drives can also pose potential data loss issues. Perhaps your friend was responsible for inadvertently deleting all of those vacation photos when you lent them the drive to see where you had been. You might accidentally format a drive, thinking that the data residing on it was also saved somewhere else.
One way to protect your USB drive is to enable write protection on the device once you have finished storing data on it. This can be done by using a hardware switch if present in your device or through modifying the permissions through operating system utilities.
You should also consider labeling and backing up your USB drives if the data they contain is important to you. A simple labeling convention can help prevent you from accidentally formatting a drive.
Incorporating your USB drives into your Time Machine backups will provide another level of data protection that you may not be using to your advantage.
