It seems I need to "initialize" (read: wipe) them in the Adaptec bios menu before being able to use them as JBOD. What the fuck?! By my defintion JBOD should means "just get out of the way and let me use my disks as they are". Does that "initlialization" mean that disks become unusable when plugged to an adapter of any other brand or model? What is the underlying format of JBOD disks. Can they be read by a straight, non-raid adapter? These hardware raid cards suck on so many levels...
