Best guess? Those 3TB Hitachi drives use 512 byte translated native 4KB sectors. The 9750-24 ie card doesn't know how to properly align partitions on such drives, and/or you're using something other than fdisk or parted to create your partitions. Currently these are the only two partitioners that can align partitions properly on 512 byte translated/native 4KB sector drives. Thus you're taking a performance hit, same as with the WD "Advanced Format" drives which have 512 byte translated/native 4KB sectors. If you want maximum performance with least configuration headaches, avoid 512B/4KB sector hybrid drives. If you _need_ maximum drive capacity, live with the warts, or jump through hoops to get the partitions aligned, or, live without partitions if you can. -- Stan _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
