Maybe the disk has a defective surface, so the error- correction kicks in. Some disks take a long time in that case, because they read the same track over and over again with slightly varying servo offsets. If the disk supports SMART, then maybe smartmontools provide some information about defects (I don't know if smartmontools runs under DragonFly, though).
