1. Hard disk failure
2. BIOS / Mother board issue
In the error page I am getting an alert like press Del to enter BIOS. But pressing Delete button was not working. So I decided to check the hard drive ,so I opened the cabinet and disconnect power and Bus from the hard drive. Then I reconnect it. Surprisingly my computer started work again and no more smart command failure message. Then after I started checking the actual reason for this hard disk smart command failed error message and the possible solutions of this error message. By going through different message boards I got an over all idea of this error message.
hard disk S.M.A.R.T command failed - Possible reasons and solutions
The main reason for this error message is hard disk failure and when the SMART BIOS feature detect this issue we will get the hard disk smart command failed error message.
SMART stands for Self-Monitoring, Analysis, and Reporting Technology for monitoring the hard drive for any kind of malfunctioning. If S.M.A.R.T detect any problems with computer hard disk it will return the hard disk smart command failed error message.
