I have one of those disks and it works for me in:
   FreeBSD 10.0-RELEASE #0 r260789

# smartctl -i /dev/pass2
smartctl 6.3 2014-04-10 r3888 [FreeBSD 10.0-RELEASE i386] (local build)

This was built from the latest smartmontools developer repository
because the FreeBSD ports version of smartmontool was broken,
see below.

The reporter had Revision 4 of the disk's firmware while mine is
Revision 2. The reported error said the IEC mode page was broken.
No surprise there, mine is too but in a different way:

[root at sas ~]# sg_modes -p 0x1c /dev/pass2

The long LBA version says the logical block size is 0
bytes. Well done Seagate!

So IMO this is not a FreeBSD error and most likely not
a smartmontools error. Also it has nothing to do with
the HBA. But I did see this when I tried to build
smartmontools from ports:

===>  smartmontools-6.0 improper use of USE_PERL5.
