I'm using Testdisk 7.1 to recover data from lost partitions. I'm copying the files directly to a USB 2.0 drive. The result from Testdisk is positive. Nonetheless, when I insert the usb drive on another computer, I do not see the files.
ls -l shows there are no folders nor files. Nonetheless, on properties, I can see the pen drive has most of its capacity occupied. The files are not hidden.
I even tried to run
sudo chown -R ... in the directory where the files supposedly are, but with no success.
What am I missing?
