I thought the same thing so I worked with the hdparm developer (Mark Lord) and gave him data two months back. There was a command he had me run (hdparm --istdout /dev/sda) that extracts firmware tables or something and he spent time looking at the tables only to decide that WD simply isn't identifying anywhere in the tables that the drive is 4K/ physical sector. With that it doesn't seem that hdparm could ever do anything automatic that would be safe. - Mark -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
