Thank you for that info, but we want to put things like Ext3 on the
device. Trying to construct a 13TiB FAT file system is probably not much

Upon further investigation it seems that the READ CAPACITY(16) request
is not getting to our device, so maybe the SCSI layer is not forwarding
them over USB.
