External USB 2.0 Harddrive

[freebsd at graffiti.net]

I have a WD external 200GB harddrive in the generic USB2.0/Firewire enclosure.  I am running 5.2.1-RELEASE
I know that the problem is with the quirks for either the umass.c or the scsi_xx.c, but have been unable to determine which quirks the drive/enclosure require.

>From dmesg
da0 at umass-sim0 bus 0 target 0 lun 0
da0: <WDC WD20 00JB-00EVA0 15.0> Fixed Direct Access SCSI-0 device

Any suggestions or other trials and tribulations would be greatly appcreciated
