Got 8" drive on PC working

Ok, I finally found an 8" drive that worked. I don't think there's a coincidence that it's half-height, and seems to have been made in the 1982 timeframe. I can't tell who the manufacturer is because I haven't unbolted it from the chassis it's installed in to check yet. I was able to format a disk mostly successfully (more on this in a bit) and transfer MS-DOS 6.22 to it. It was pretty nifty booting DOS on my PC off an 8" drive ;) So anyway, when I was formatting the disk, it didn't seem to like the last 4-6 tracks or so. Above the clatter of the noisy fan (bad bearings) I could hear the head recalibrating. When the format finished, it reported 107520 bytes in bad sectors. This comes out to 210 bad sectors (assuming 512 bytes per sector) which comes out to some weird number of tracks. Aren't there supposed to be 26 sectors per track? The main hurdle has been jumped, so I'm in good shape at this point.
