I have been using the My passport Essential that is of 500 GB and has been using it since long. I have been using the Intel Pentium Core to Duo processor in the system of the desktop that I am using, to which I use to connect the potable of My Passport Essential in it. The working of the potable HDD was good and has no issues in it. But the main thing is that just recently a issue has been faced by it, and I donít know what is the main issue that is being faced by it. Whenever I connect the HDD it is showing me the space of 2TB that is being said to be unallocated in it. I am using the potable HDD that is of 500 GB and it is showing me this kind of the space in it, and I have no idea what is this display in it.
