hdparm: HDIO_DRIVE_CMD(identify) Failed: Inappropriate Ioctl For Device

Posted on in Categories , , , , , , last updated August 23, 2009

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?
