OK. When I did a -Clear and recreated the drive as a single disk raid0 volume, the data was still there, but I wanted it to go away. > On Dec 15, 2011, at 11:03 AM, Hugo Silva wrote: > >> On 12/15/11 15:28, Hugo Silva wrote: >>> As Borja said, part of the difficulty is the H700 abstracting a single >>> disk as a RAID-0, I guess.
