But decided if I go this route, I might as well bounce the box and simply use the SCSI's BIOS routine to re-format all 3 drives. So that's what I did, and guess what - yep, you guessed it; every thing worked (gstripe(8)) as it should have. So good news, nothing wrong within GEOM, and family. :) Thank you again for taking the time to respond Miroslav. --Chris > to clear the begining of the disks.
