Yes - but this depends on the medium used. Flash storage media like SSDs have their own controller which does bad block mapping on their own and use spare blocks (usually a few percent of the capacity are reserved for this) as substitute for defect ones. However SD cards are quite "dumb" and 100% of the capacity is used for data - so bad blocks need to be recorded as part of the filesystem during "long" formatting. -- Arno Welzel https://arnowelzel.de
