I connect the usb hdd to my lenovo x220. While copying big mp4 files over to the usb hdd, the x220 simply stopped responding; not even ctrl-alt-del gives the Task Manager. So I just pulled out the hdd n since then quite a number of the mp4 files cant play on my dedicated player: gives play error or even causing the player to reboot.
I m not going to do 'chkdsk /f' on this usb hdd as the last time I did this on a WD usb hdd, it got much worse n lost all data. What is the next best things to do to recover?
