I'm double checking this. I actually ran badblocks the other day but did not save the output. According to some documentation, and others on the web that this repeated warning is always the same sector, and according to the articles I saw is that it had been remapped. However, I just ran a smartctl assessment, and 198 is showing 0. In the past it showed 1.
