About USB data recovery

USB data recovery refers to the process of recovering lost data from USB drives such as pen drive, USB flash drive, thumb drive, memory cards, jump drive, external HDD and other removable data storage devices. USB drives have a large user base throughout the world, as they not only store all sorts of files for users, but also, they can be carried to anywhere easily. It is because of the portability that USB drives are more likely to get corrupted or lose data. No worries. It is common wisdom that in most cases recovering files from USB drives is easy to achieve.

Common reasons for USB drive data loss

USB drive data loss can occur for various reasons, and there are some of the most common causes you may encounter.

  • Accidental deletion: the human error is not easy to avoid and many of us might delete important files or folders from USB drive by mistake. These deleted files won't be put into Recycle Bin, which works the same as the Shift + Delete.
  • USB drive gets formatted: you may format a USB either on purpose or by mistake, and the result is removing all data off the drive. As long as you do not perform a full / slow formatting and do not store data to the formatted drive, you have a good chance to get data back.
  • The USB drive becomes RAW: When file system of your USB drive turns into RAW, you can neither open the partition nor access files in it. If you double click the drive in Windows File Explorer, you will get an error message such as "You need to format the disk in drive before you can use it. Do you want to format it?" "Drive is not accessible. The parameter is incorrect." "Drive is not accessible. The volume does not contain a recognized file system. Please make sure that all required file system drivers are loaded and that the volume is not corrupted." "Drive is not accessible. The file or directory is corrupted and unreadable."
  • Virus: USB drive can be shared among users and then used on different computers, which makes it easy to infect virus or malware. To minimize this risk, you need to enable Windows Defender or install third-party antivirus software on your computer.
  • Physical damage: USB drive can also develop bad sectors and fails to work. Moreover, other physical damage can also occur for example, drop it to the floor.

What should you do before USB drive data recovery?

It is understandable that you may get anxious when USB drive data gets lost, and yet you should pay great attention to following actions in order to get the best chance of USB drive data recovery.

  • Stop using the device: It is crucial to stop using the USB device at once when you realize the data loss issue. Do not store any data to the drive or edit current files. If you continue using the device after data loss, you may overwrite recoverable files, making them permanently lost.
  • Do not format the USB drive: Formatting is not helpful for data recovery task, and sometimes it may make the issue worse.
  • Do not run CHKDSK: CHKDSK can help us check and repair errors in file system, but it does not work as expected in many cases and even causes further damage to the drive, for example, lost data cannot be recovered with original directories. Hence it is not advised to run disk checking before all files are recovered.
