Problem installing SATA hard drive
I wanted to install an external hard drive to retrieve data from another computer.
So i plugged the second drive and started my computer and then we see the windows logo it stops responding and nothing happens.
So i tried unplugging and it's working again. so i wonder if it's because on the two hard drive there is an operating system that is installed or if the hard drive that make this problem.
I am on windows 7.
