Usually, the hard drive can be successfully connected to a computer and shown in Windows Explorer but loads forever and finally unresponsive. Actually, this issue is quite common and may be caused by some reasons including logical errors, bad sectors, insufficient power, etc. This example tells you a case about external hard drive taking forever to load. When I go to Disk Management, it will load forever as well, as though it is trying to access the HDD but it is not able to.' Tomshardware
