Just like a hard drive, a USB flash drive stores all its data in the memory & the operating system can, later on, fetch this data when required to be accessed. There are two main reasons that may turn your USB drive data inaccessible. Such as if the drive is unmounted improperly from the port, it can lead to data corruption. Another reason can be invalid data in the Master Boot Record (MBR) or Partition Boot Record (PBR) or directory structure on the USB drive. So, let’s explain how to perform a flash drive data recovery.
There are two main reasons why your USB may not be working. Hardware issues or Logical issues. We will discuss both.
