I have some files on a external hard drive that i want to move as i need the external hard drive to extend my main hard drive as it is full. my files on the hard drive are about 60gb so cassettes look good as there cheep and i heard you can get about 13gb on each one. so i need an adapter so i can put my files onto the cassettes and i would like it as cheap as possible i don't really fancy buying a camera so i can do this.
