Please, its urgent. Is it possible to use another wire? I don't have money btw.
Put a coat hanger on it and wait for a thunderstorm.
Troll patrol a brilliant answer as far as humour goes. Your computer would normally have spare power leads in it in case you want to add other drives. if not then try taking one from your CD rom and plugging it to your hard drive. Only problem here is your system may boot from the cd rom.
Disconnect the power cable to the CD or DVD drive for a while and use it on the hard disk for now if you have no money. That way you can use it.
