3 TB disk troubles

     I recently bought a 3 TB external hard drive.  I attached it to the
Firewire (400) bus and waited for my 8.2-STABLE i386 system to recognize it.
After a small flurry of Firewire protocol messages, the kernel eventually

Feb 12 23:35:42 hellas kernel: da2 at sbp0 bus 0 scbus0 target 1 lun 0
Feb 12 23:35:42 hellas kernel: da2: <Initio INIC-1615P 0101> Fixed Direct Access SCSI-0 device
Feb 12 23:35:42 hellas kernel: da2: 50.000MB/s transfers
Feb 12 23:35:42 hellas kernel: da2: 2861588MB (5860533167 512 byte sectors: 255H
 63S/T 364801C)

So far, so good, I thought.
     Next I tried to use gpart(8) to set up a partition table.  However,
gpart, gpte (from sysutils/gpte), diskinfo(8), et al. only see the device
as a 2 TB drive.

hellas# diskinfo -v /dev/da2
        512             # sectorsize
        2199023253504   # mediasize in bytes (2T)
        4294967292      # mediasize in sectors
        0               # stripesize
        0               # stripeoffset
        267349          # Cylinders according to firmware.
        255             # Heads according to firmware.
        63              # Sectors according to firmware.
                        # Disk ident.


     I have searched the archives of this list and several others, but
haven't found anything helpful.  This disk is *not* intended as a boot
disk, just data storage.  Is there any hope of using its full capacity?
Or have I effectively bought an overpriced 2 TB drive?
     Please Cc: me directly in any replies because I am subscribed to
the digest form of this list and would like to see responses without
having to wait up to 24 hours. :-)  Thanks in advance for any help!
