I had something like this once, it caused the data in the drive to 
become corrupt. This wasnt smartmontools' mistake. I think there was a 
problem in FreeBSD. The controller was Adaptec AIC7902 Ultra320 SCSI 
adapter. But now it seems to be fixed (I am on 6.2-STABLE, I think I was 
on 6.1 then).

Anyhow, it might or not be the same problem that I had but I suggest you 
to proceed with caution, oh by the way, do you see any errors reported 
by the operating system when you run smartctl repetitively on the drive? 
or any slowdowns etc.?

Thanks,
