diskutil eraseDisk failed, exit status 1
However, if I use the partitions rather than the full disks themselves, it works.

Each 3TB drive has its own power supply and its own eSATA connection to a NewerTech external SAS controller running current drivers from the NewerTech web site (newer than the OWC web site). I have a Mac Pro 5,1 with 32GB RAM running the latest iteration of Mountain Lion.
They work fine using Disk Utility to create an HFS software RAID, or as individual HFS-formatted disks.
Any ideas what I'm doing wrong and what I'd need to do to be able to use the whole disk rather than just a partition?
Thanks,
