Restoring files from a damaged flash drive
Restoring files from a damaged flash drive can be a difficult process, but there are several methods that you can try.
1. Connect the flash drive to a second computer or USB port: Sometimes the cause of the problem may be in the USB port on your computer. Try to connect the flash drive to another port or even to another computer and check if it works there.
2. Use data recovery software: There are many free data recovery programs available from damaged storage devices, such as Recuva (https://www.ccleaner.com/recuva) or TestDisk (http://www.cgsecurity.org/wiki/TestDisk). Just make sure before using these tools to save all found files to a new location - this will help prevent possible data loss when overwriting old files.
