I tried opening up Disk Utility on my Mac, but it just spins forever trying to mount the external hard drive. It can be read on a Windows laptop (after Windows automatically fixed an error). When I plug my WD Passport Ultra 4TB external hard drive WDBBKD0040BBK-0A (with 2TB of family photos) into my MacBook Pro it has fast flashing of light and can't be mounted.

After more than an hour I came back and the drive showed up on my Mac again. I plugged in again into my MacBook and left it there. I have no experience with partitioned external drives, so I know not if this could suggest that they are actually two separate physical units (something "hacked" in the SATA-to-USB controller, maybe?) or it is just me unable to properly erase the hard drive and forget about that damn VCD.After about 3 weeks. One strange thing I noticed is that even when the drive is unmounted, I have the option to mount separately the virtual CD and the drive itself. I tried with both fdisk and parted, but I may have done something wrong.


I also tried to change from MBR to GUID and vice-versa with no success. under OS X, I tried to initialize the physical drive several times with Apple's Disk Utility.Whenever I plug this device into a computer, there is a virtual CD unit that pops up called "WD Unlocker", and I'm trying to remove it physically, instead of just hiding it (I found many guides on this, and by the way none of them worked). I have a WD My Book (3TB storage, USB 3), and just like many other enthusiast owners of this external drive, I'm trying to get rid of their crapware.
