I bought a WD passport for my car. My head unit has USB on it so I went that route.... everything works in my car, and the single USB cable thats also supposed to power this fuckin drive, works on laptops and work PCs.... but my desktop? NOPE.... I have 2 diff cables, 1 thats a Y type USB cable to plug into 2 ports that go into 1 mini b for the hdd, and 1 normal to mini b cable. The single cable works fine with everything, but even the Y cable, doesnt work on my desktop.... it loads and unloads and repeats constantly until I unplug it.... I cannot figure this out.
