How to Fix a USB Flash Drive That's Write Protected?

Files and data are often lost due to a crash or an infection by a virus. If the information is not backed up it can be lost forever. USB flash drives, along with CD's, external hard drives and on-line storage, are an important tool for backing up data stored on your PC. Like any storage device USB flash drives can be write protected. This means that the data on the device is protected from being erased or changed. Settings on the USB flash drive protect the information, but can be altered.
