The hdparm command, using options to probe a drive, will exit 0 as if the
probe was successful but the output says otherwise.

Reproducible: Always
Steps to Reproduce:
1.hdparm -C /dev/hdc
	where /dev/hdc is a drive that is working that you
	want to obtain the status
2.put the drive to sleep:
	hdparm -Y /dev/hdc
3.pull the power plug on /dev/hdc
4.hdparm -C /dev/hdc
5.echo $?
	

Actual Results:  # hdparm -C /dev/hdd

/dev/hdd:
 drive state is:  unknown
# echo $?
0

Expected Results:  # hdparm -C /dev/hdd

/dev/hdd:
 drive state is:  unknown
# echo $?
1			(or some other non-zero exit code)

Other hdparm commands such as:

# hdparm -Y /dev/hdd

/dev/hdd:
 issuing sleep command
 HDIO_DRIVE_CMD(sleep) failed: Input/output error
# echo $?
0

also exit 0 when an error occurs.
