If it's more recent, then it almost certainly does internal bad-block remapping on its own. That means that if bad blocks are becoming visible to the operating system, the disk has hundreds or thousands of bad sectors, and is on its way to the grave. This would be more serious if the errors were occurring on writes rather than reads, but there has already been data lost, and some of the data on the disk is known to be corrupted. If the original poster has a hard disk that predates the 486 chip, then I apologize for having given a possibly incorrect answer.
