Stuart, Walt:
I've tried using bulk erasers on DAT tapes in the past with not much
success. It seems that if all you need to record are 1s and 0s, you
can hit the tape pretty hot. (I even tried it with an eraser designed
to degauss 35mm mag film w/ no luck. I'd go with Walt's suggestion:
just re-record the tape start to finish.
