Have you tried HDD Regenerator? It rewrites the HD with a reverse polarity if I understand it correctly. Does not damage data already on the drive.

Google it and do some research on it.

thanks, what frustration here. I can't believe Apple would overlook bad sectors, but that appears to be the case. I don't get it, as bad sectors have always been my #1 hardware problem.

nice writeup. i experienced similar problems, yet the bad sector seems to be on the firewire drive i'm writing too. it will hang on the bad sector for hours and then finally file instead of moving to another sector. the zero erase in osx will fail also. it's just one sector, the rest of the drive is good. how can i repair this or get around it? so far the only solution is 2 partitions and then somehow the bad sector ends up in a place in 1 of the partitions that isn't used. is there a bad sector repair utility for osx?
