I have a 1 tb hdd which was detected by my system having windows 8.1 earlier but now its not detected checked in every port and the led keeps on glowing and even a sort of vibrations in the hdd connected .No problem with usb port the port works well with other external hdd of same specifications.It is not being detected by my system at all and even tried on other laptops as well but same problem.Any suggestions or help from your side is welcome.The warranty has ended just a month ago.
Thanks
Regards
