Recovering Files from a Logically Corrupted USB If you start to notice any of these signs and you can still access your data, it’s highly recommended that you transfer all data to another storage device for safekeeping. This isn’t to say the files themselves have been corrupted, but instead, the USB itself has sustained some form of logical or physical damage that now prevents you from accessing your files. ⚙️ Corrupted USB – When an entire USB becomes corrupted, the contents on the USB will no longer be accessible.These can still be recovered from a USB, but the actual file or folder will need to be fixed in order for you to view it again.

Any attempt to open it will be met with an error message. A corrupted file or folder would have sustained some form of damage that has caused it to become unreadable.

📁 Corrupted file or folder – A corrupted file or corrupted folder on a USB is singular, meaning corruption is isolated to that file or folder only.

But, we first need to understand the difference between recovering corrupted USB files from a USB and recovering a USB that has been corrupted, as the two are not the same: Is It Possible to Recover Corrupted Files from a USB? This can be considered the natural aging of a flash drive and means that it becomes more susceptible to corruption near the end of its life cycle. NAND flash memory, over time, begins to wear down as a single memory location can only be overwritten so many times.

📉 NAND memory wear – During its lifetime, your USB is going to go through thousands of read/write cycles.

This is why it’s important to store flash drives appropriately, in a temperature-controlled environment.

💧 Exposure to harsh conditions – Exposure to water can cause the electronics to short, and environments with salty air can cause the contacts to erode.

🔌 Sudden power loss – If power is lost while the USB is in use, it can cause all active operations to halt, causing either the files or the USB itself to become corrupted.

Because of this, you always need to eject the USB from the computer before removing it. If you remove the USB from the computer while there is a read/write action being performed, it can cause file corruption.

💥 Removing it before ejecting – When a USB is plugged into a computer, there are various processes happening in the background.

While the exact reason why your drive is corrupted may be difficult to determine, here are a few of the most common reasons: There are many different reasons why a flash drive can become corrupted.

If you have a physically damaged USB and are not comfortable attempting the physical troubleshooting methods we touch on later in this article, seek out the services of a professional. This article will focus primarily on recovering files from flash drives that have sustained logical damage.
