Before I got this PC I used to have an old iMac and once I got this PC, I wanted to transfer all my music to it. I first plugged the external hard drive into my old iMac and it worked fine. I managed to transfer all of my music over to the drive. However, once I plugged in the external hard drive into my PC, it didn't show up anywhere but device management. It doesn't show up in disk management or in "Devices and Drives". Any help would be appreciated.
