Prsuming the cable is ok, this sounds like you have some dust/dirt in the
drive, or the tape is bad. Cleaning the drive is not so difficult. just
open the metal casing, the you see some LEDs. (3 on the top, 1 on the
bottom off the drive) Clean them. Sometime it is enough to blow some high
pressured air in the direction of the LEDs. This should help in most cases.
