Put your HD to external crate then plug it to your running notebook, it's plug and play so usually it should detect it right away.
slave the hdd into another pc and browse for your files if you hold locked them you may never get them posterior
Remove the harddrive and install to another PC as slave harddrive. PC can install two harddrive, from there you can stretch out the harddrive that you have install only just.
