I've seen high reallocation numbers on a few Seagate drives over the years. Of course, I've had every Seagate drive I've owned fail. All of them. I have a box od WD IDE HDDs that still work fine, but more recent SATA Seagate HDDs in that box are all junk. Not trying trying to flame Seagate, just my experience. Others have the opposite happen so YMMV.
