It could be bad sectors / damage to partition table or file system structure in such away that it will hang the system. I suggest downloading manufacture disk drive test or you can try the partition repair/data recovery software by “Salvage Data Recovery Lab Inc”. You can find it easily if you just run a search in google it’s name… Instructions are clear while installing. Connect your drive as secondary drive on the system (not external) / or even primary and let that software run. That at least will let you know if drive is ok.
