While running the command hdparm to check the hard drive speed,we are receiving the error message that hdparm is not found.
First check if the hdparm RPM is installed or not by using the following command.
rpm -qa | grep hdparm
If rpm is not installed then install rpm for hdparm as per server OS and bit i.e. 32 bit or 64 bit.
Now run the following hdparm command to check the server disk reading speed.
hdparm -t /dev/sda1
