Here is what happened, I was watching a video on my hard drive and moving files to it, suddenly it frozen, so I unplugged and plugged it again, but it did not work, it did not show on (my computer) window, but it is shown in (device manager), first as a (working probably device), then it is shown with a yellow mark and the device status is (This device cannot start. (Code 10) {Operation Failed}The requested operation was unsuccessful), and when I try to make the usual troubleshooting, it changes to (an indefinable device), and Windows give me a message says that Windows cannot recognize the device because it is malfunctioned, for the hard drive itself, it starts with a flashing light, then it stops flashing and becomes still, after few seconds, I hear a tek sound comes from it, but the drive still working with less sound than usual, I have tried all of the solutions which was written for the similar problems, and still the same, so what should I do?
