+ The downside of leaving this option disabled is that if bad blocks
+ are detected by Linux, they will not be recorded in the BBT, which
+ could cause future problems.
+ Once you enable this option, new filesystems (INFTL or others, created
+ in Linux or other operating systems) will not use the reserved area.
