Check the power supply, for stability, voltage level, noise etc. (especially if the errors have a some randomness about them.) I've missed a few exchanges on this thread, but what (if known) happened to the drive immediately before the trouble started?  Or, between it's last known good state, and the state it's in now.   ANY unscheduled "events"? Is it making any "unusual" sounds, frequent servo resets, squealing or ticking noises.  Does it vibrate?  (They all do to an extent) but if it's significant, like you can feel it when holding it in your hand while it is spinning, the drive may have been dropped and a platter has moved off centre on the spindle.  I've a portable NAS drive that's happened to, it runs hotter as a result of the extra work the servo has to do to track the off centre cylinders!. Try it in different positions, laying flat, vertical etc, at an angle all orientations.   But don't move it while it is spinning. If the errors seem to be getting more and more frequent, it may be on the verge of dying anyway. I'd still go for the Spinrite option.  If it works, great, read the contents and pension off the drive for a new one (but Spinrite that before use!)  If it doesn’t help, contact GRC it is likely they will refund you, I know of someone personally who had that happen.
