First I found 2 lost partitions, but from one of them nothing was recovering.

Then after deep analyse, I find this unable to copy from partition again.
Now I am able to copy from directories I was unnable before, but when I navigate those with arrow keys it make beep sounds. Constantly. What it mean?

You have a stuck key.

I double checked it good sir.
