My External Hard Drive (WD My Passport 500 GB) does not show up in my computer. First, I went to device manager and it said the there are no drivers installed. So, I went to the site and downloaded the driver for it. The driver installed successfully. And when i check on the device manager there are no more errors or problems to be found, driver is already installed and it said device is working properly. But when I checked in my computer, the hard drive still does not show up. I went to the disk management but I cant change the drive letter of it. Disk is not unknown and not initialized. I already restarted my laptop but nothing happened the device still does not show but it says device is ready to use when plugged in. What should I do now?
