Now, the 5 VDC supply of power from a USB2 port is limited to 0.5 amps max, but USB3 increased that limit to 0.9 amps. Almost all Laptop Hard Drives require more than 0.5 amps, but not more than 0.9.

It looks like your WD My Passport has 2 unallocated partitions, meaning that these capacity are not accessible or used, you can basically make that space available by formatting the volumes.As to why you are unable to access those files on the 259.79 GB partition is most probably because you have somehow lost the drive letter & path.
