Greetings! Please add me to what must be a very large list of netadmins who will do their best never to purchase another WD product - all because YOU will not give me control over a device that I OWN - I paid you for ownership of the drive, and you put a non-removable partition on there without warning me in advance. If I had known the virtual-cd partition was there, I would never have purchased these drives.
Welcome to the WD Community.
As a recommendation, see the following link for instructions on how to remove/hide the vcd partition on the portable unit.
How to remove (disable / hide) the Virtual CD (VCD) for Windows or Mac OSX on a WD My Book or WD My Passport
it only takes seconds to remove it :confounded:
