By typing chkdsk
And what the hell is that supposed to impart to the original poster? Type chkdsk in a word document, notepad, regedit? If you have no valuable information to give then DON'T waste your time and the time of others. Put your brain in gear, if you actually have one, and compose a proper reply. If you only think you know how to start chkdsk, then keep your useless information to yourself. MALAKA!!!!!! greek for wanker by the way.
