I'm a little fuzzy on the format of an ATA "QWORD" for the SCT commands. http://www.t13.org/Documents/UploadedDocuments/docs2006/D1699r3e-ATA8_ACS.pdf Assume a QWORD LBA of 0102030405060708, how is that arrayed in memory when the bufer is formatted and sent? Bytes 0-3 = action, etc Byte04 = 08 Byte05 = 07 Byte06 = 06 Byte07 = 05 Byte08 = 04 Byte09 = 03 Byte10 = 02 Byte11 = 01 or Bytes 0-3 = action, etc Byte04 = 01 Byte05 = 02 Byte06 = 03 Byte07 = 04 Byte08 = 05 Byte09 = 06 Byte10 = 07 Byte11 = 08 or the wierd ATA endien byte/word shuffle instead? How would that be laid out? -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
