Hello. When I try to plug in my external hdd in usb, a strage sound come from it (like clock ticking). It doesn't appear in my computer neither in disk management. I can see it though in device manager > disk drives. It also doesn't appear in bottom right at safely remove. After I terminate explorer and start it again it appears there too. Another behavior is that in the past when I was trying to boot, it was blocking the procedure and wouldn't let me in unless I unplug it and restart. ( it was working afterwards if I plug it in while I am in windows). It seems that bios dont recognize this hdd either. The problems with this hdd started when I bought a new pc 2 months ago. I think I never had problems in my previous pc. IS there anything I can to fix it ? I never hit it or moved it from its position. thank you for your time.
