According to the handbook you need all of the following drivers:
scbus da pass uhci ohci ehci usb umass
Don't know if this helps, but 512K sectorsize on usb 3 seems to work fine here:
%diskinfo -v da0
da0
512 # sectorsize
1500301909504 # mediasize in bytes (1.4T)
2930277167 # mediasize in sectors
0 # stripesize
0 # stripeoffset
182401 # Cylinders according to firmware.
255 # Heads according to firmware.
63 # Sectors according to firmware.
NA05EA2N # Disk ident.
dmesg:
ugen0.2: <Seagate> at usbus0
umass0: <Seagate FreeAgent GoFlex, class 0/0, rev 3.00/1.00, addr 1> on usbus0
umass0: SCSI over Bulk-Only; quirks = 0x4100
umass0:8:0:-1: Attached to scbus8
da0 at umass-sim0 bus 0 scbus8 target 0 lun 0
da0: <Seagate FreeAgent GoFlex 211> Fixed Direct Access SCSI-0 device
da0: 400.000MB/s transfers
da0: 1430799MB (2930277167 512 byte sectors: 255H 63S/T 182401C)
Plugging it in adds only da0, da0s1, and ugen0.2 to /dev
My disk is bigger than what you're dealing with but not the big sector size;
can't say about that difference.
