Hi all I have a Western Digital Nasware 3.0 WD20EFRX 2tb hard disk, the problem is that I can not access it on the hard disk, it says '' access denied '', I would like to know what programs are used and what instrumentation is needed to make the diagnosis, I would like to know that the equipment is also used in case of physical damage, because I tried via software and I could not, I await your answers thanks
