USB flash drive data recovery

Overview of USB flash drives

USB flash drives, also known as pen drives, thumb drives, jump drives, flash drives, or memory drives, is a small and ultra-portable data storage device. They are often used to store important files and backups, carry favorite settings or applications, launch an OS from a bootable USB. At present, USB flash drives have nearly replaced floppy drives, CD, DVD and BD disc for data storage purpose, considering how large, fast, inexpensive and durable they have become. They can support modern operating systems such as Windows, Linux, macOS, and other systems.

Unlike traditional hard disks, USB flash drives are hard to stop working as they have no moving parts to wear out. But there are still times when USB drives can become corrupted and unreadable as a result of sharing the drive with many different computer systems. Then all data stored on the drive become inaccessible.

Reasons behind USB flash drive data loss

There are so many reasons due to which data get lost or become inaccessible. Knowing these reasons would be helpful to troubleshoot and prevent certain USB drive failures. The following are some common ones:

  1. Accidentally delete files from USB flash drives. If files are deleted by using the "Delete" button on the keyboard or selecting "Delete" or "Move to Trash" from the context menu, these recently deleted files can be easily restored from the Windows Recycle Bin or the Mac Trash. But when you delete files in another way, for example, with the key shortcut "Shift + Delete" on Windows or "Command + Shift + Delete" on Mac, such files are erased at once. You won't see these deleted files in the Windows Recycle Bin or Mac Trash and you need to use a deleted file recovery software to restore them.
  2. Unplug USB flash drives forcedly when dealing with files. If you simply pull your USB flash drive while data is being written to it, for instance, while you're moving files to it or saving files to it, you are asking for trouble. You might suffer from data loss, software crashes and so on.
  3. Format USB flash drive without having a backup. Sometimes accidental format might occur due to a mere human error. Meanwhile, you may decide to perform formatting when receiving the disk not formatted error on Windows or the disk not readable on Mac. When you format a USB flash drive, the operating system will erase all data on the disk.
  4. USB flash drive is infected via virus. In most cases, virus attack can result in data loss on a USB flash drive, a memory card or other external drive. If you plug your USB flash drive into an infected system, download and install cracked software on the drive, then the USB will be infected as well. Those computer viruses are programmed to harm your computer and storage device by damaging programs, deleting files or reformatting the hard drive.
  5. Bad sectors appear in USB flash drives. It's possible for bad sectors to develop and corrupt some of your data. In general, bad sectors can are caused by software issues or physical damage.
  6. Lack of power supply in the hub port. If your power supply is not able to provide adequate power to USB flash drives, they will stop working.
  7. Faulty USB port or cable. Many a time, it happens that the port or cable of your USB flash drive is damaged. As a result, the drive doesn't get detected by the system, making it impossible for you to access your files.
