Thank you
Hello,
If your external hard disk is still recognized by Windows:
Test your hard drive with CrystalDiskInfo
Try to recover data from the hard disk with Testdisk-Photorec:

If your external hard disk is not recognized by Windows:
Check the USB connection cable
See if it appears in the disk management
If it is no longer recognized and no longer works, it will be necessary to ask a specialized company to perform a data recovery, this operation is quite expensive.
