531	  data on your device (created by non-Linux tools such as M-Systems'
532	  DOS drivers), your data might overlap the area Linux wants to use for
533	  the BBT.  If this is a concern for you, leave this option disabled and
534	  Linux will not write BBT data into this area.
535	  The downside of leaving this option disabled is that if bad blocks
536	  are detected by Linux, they will not be recorded in the BBT, which
537	  could cause future problems.
538	  Once you enable this option, new filesystems (INFTL or others, created
539	  in Linux or other operating systems) will not use the reserved area.
540	  The only reason not to enable this option is to prevent damage to
541	  preexisting filesystems.
542	  Even if you leave this disabled, you can enable BBT writes at module
543	  load time (assuming you build diskonchip as a module) with the module
544	  parameter "inftl_bbt_write=1".
