My Laptop Harddisk contains bad sector so i got a new harddisk...... But the problem is that i have to get backup from that driver i have tried to attach on USB drive but its not working i mean not being accessed I have applied external power as well as given the HD internal power from the system but no luck in both cases. Note that there is no lan card in the laptop so any suggestion for getting that data.

Oh yes if i use old harddisk i cannot load windows, i can only access its d and other drives where the data is by booting frm DOS.
