Of course, if you have a bad sector it may be that you can't possibly write to it such that it will read back the pattern you want. The formatter in question may be failing to write to those sectors, or writing zeros to them. Also, even if the formatter did write the pattern you specifed to a bad sector, it may be that it is unable to read it (because it's bad), and returning zeros. I don't know anything about HSCs and RA82s though, so this may have nothing to do with it. Cheers, Eric
