compile tar.gz

When I run hdparm -tT /dev/sda command under CentOS / RHEL I get the following error on screen:

/dev/sda:
Timing buffered disk reads: 908 MB in 3.00 seconds = 302.39 MB/sec
HDIO_DRIVE_CMD(null) (wait for flush complete) failed: Inappropriate ioctl for device


How do I fix this problem?
