no, the 3ware controller must format the disks prior to use. I've never
seen a raid controller that supported this.

I've used 4 3ware 6800 series controllers, they presented each raid
array as a scsi device, if only 1 raid array, then /dev/sda the 7000
series controllers may be different but I'd be suprised if they were
in this regard.
and just to remind you, raid0 offers no protection, if 1 disk goes in
a raid0 array, all data is lost. I reccomend MINIMUM raid 1, PREFERABLY
raid 10.
