I have a WD My Book 8Tb external drive that was working perfectly. I have nearly filled it so i bought a WD Elements 8Tb drive. Yesterday when i plugged in the new external hard drive in, the WD My Book external hard drive suddenly became read only and virtually unusable as a consequence. I downloaded WD Discovery which said that it was read only. I clicked on the install driver link, which lead me to HFS+ For Windows Paragon Software, which i have installed on my local drive and restarted my machine but the My Book drive is still read only.
Any help would be appreciated as being read only, my WD My Book external hard drive, is virtually unusuable.
