Here hard drive access is fast and quiet. 2. on a 5G hard drive where fbsd uses only half the drive. Other OSs share the rest of the drive. This is the problem installation for fbsd. The other OSs both have quiet, fast disk access on this drive. Conclusion: softupdates status would be the same on both disks; enabled, I think. So I don't think that this problem involves softupdates status.
