When you bundle the drives together, the resulting device will have totally scrambled the underlying NTFS filesystems. The second option is how md RAID is supposed to work - you bundle together the disks into a single array, then format that. Where are you getting the "write-protected" errors? Are you trying to format the exported iSCSI device from a remote system? Certainly the RAID device can be formatted directly, but I've no idea how the iSCSI affects things.
