Oh, right, related: it's almost a complete certainty that the drive's *real* blocksize is 4k, but has internal code to present it as 512bytes. When you format the drive, be 100% sure to align it correctly: for parted, tell it 0.0TB, which will put it at 1M. The alignment really *does* make a difference in access and throughput speed. mark
