You can use Quarterback Tools, it creates also a "bad.sectors" file assigned to this bad sectors. The backdraw is that you cannot reorganize this disk nor change its filesystem (i.e., FFS to SFS)
A permanent solution is to add bad sectors through an old HDToolBox from AmigaOS v3.1, but this program not always detects bad sectors correctly (I know because I had this problem with an 2GB IDE HD).
Anyway, I managed to find a solution using both programs, QBTools and HDToolsBox from AOS3.1, and entering the bad blocks manually. If anyone wants it, just ask.

Enviame un mensaje a mi dirección personal (amiga arroba ono punto com) y te enviaré el método que ideé para introducir los sectores defectuosos en el HDToolBox del AOS v3.1. Si frecuentas la lista CasaAmiga, igual lo tienes ya, lo envié alli hace ya algún tiempo.
Saluditos,
