Internal hard disk trouble any solutions?

Well I left a laptop on overnight with its new charger and when I tried to boot it up the next day it got to the Samsung screen and no further at the bottom is says f2 setup or f4 recovery and I have tried both of these even with the system restore disk in and it appears to think but actually does nothing. I removed the back to have a look and everything seems normal, removed the hard disk and switched it back on and could enter setup but of course do nothing else. I tried the youtube trick of putting it in the freezer but still no joy. I then removed it and tried it in a different laptop but it would only claim that the hard drive is not installed. Should I give this hard drive up for dead or is it worth buying a cable and trying connecting it as a slave to recover the data?
