    Tech Support Guy System Info Utility version 1.0.0.4
    OS Version: Microsoft Windows 10 Home, 64 bit
    Processor: AMD A8-4500M APU with Radeon(tm) HD Graphics, AMD64 Family 21 Model 16 Stepping 1
    Processor Count: 4
    RAM: 5602 Mb
    Graphics Card: AMD Radeon HD 7640G, 512 Mb
    Hard Drives: C: 569 GB (512 GB Free); D: 25 GB (3 GB Free);

    If I buy a USB 3.0 external hard drive that comes with a 3.0 cable, can I plug it into a 2.0 port on my computer? I realize it would run at the slower speed but will that even plug-in to the 2.0 port and work?

    It should. They are backwards compatible with 2.0.

    Thanks for your reply Valis - I wasn't too concerned about the backwards compatibility speed issue but more about the 3.0 cable (typically with the blue colored inner part of the cable, plugging into a 2.o port.

    Thanks again(y)

    As valis said, USB3 is backwards compatible with USB2.
    My Realtek wireless adapter is a USB3 model and is connected to a USB2 port in my old Dell desktop, and it works fine.

    My external Usb 3.0 hard drive works when plugged into a Usb 2.0 port.
