Me too, but it's kinda tricky...

The Toshiba NAND flash we use comes from the factory with the bad blocks already marked (they may grow more bad blocks, but the initial ones are identified during manufacturing testing). If you erase the chip without saving the information first, you lose that valuable information. You should check with your supplier to see how they handle it.
