Why can’t I access my 1TB external hard drive?
Question by Jaja Zol /

I have a 1TB external hard drive. When I plug it in my laptop’s USB port it recognizes the hard drive. But I can’t open it. I receive an error message “The Parameter is Incorrect” or “The device cannot be accessed.” What does this mean and how can I fix it?

    just format it. It sometimes happens for new mass storage device. It jst happened to my new hard drive. If you can’t format it normally, do it from the boot menu and after that when you try to open it with normal windows it will ask you for formatting automatically, if not, do it manually….

    If it’s new, format the drive. If you have things you want to save, take them out with a special recovery software, then format it.

    Try to uninstall the driver from the device manager, reboot and reconnect hard drive so that Windows OS detect it an install a clean driver.
