NAND flash can always get bad sectors after some time, thats normal for memory like this.
It should not hurt you because the system will mark those sectors as "BAD" and will not use them anymore once it got detected as *bad*. So there is really no need to repair them (you can't even do it). The system will mark them as bad and not use them anymore on next image-flash. You can only get a problem when you have hundreds/thousands of bad sectors, then the flash would be bad. But 4 bad sectors are really normal for nand-flash chips and no reason to get panic.
The problem must be something else, not those bad sectors. My old DM7025 also has a bunch of bad sectors, but no problem here, box works fine.
