Reason & Solution For Hard Disk SMART Command Failed Error

Yesterday night I encountered a strange error on my computer. I couldn't boot my computer properly and instead of OS window I was stuck in an error page, Hard Disk SMART Command Failed. Other than Tab key, no other keys were working.It was a confusing situation because whenever I reboot my PC, I was going back to the same error page like I was in a loop. I started counting the possible reasons for this particular warning and the major possibilities came in to my mind were :
  1. Hard disk drive (HDD) failure
  2. BIOS / Mother board issue
On the error page I was getting an alert like press [Del] to enter BIOS. But Delete button was not working because it was not responding due to the error. So I decided to follow my way of troubleshooting and started with Hard Disk Drive. I opened the cabinet and disconnect power cable and Bus (cable which connects motherboard and peripheral devices) from the HDD. After reconnecting them, my computer started work again and no more failure messages. I was wondering whether I fixed the error Hard Disk SMART Command Failed on my computer or it was just a workaround. So I decided to spent time to research about this issue.

Reasons for Hard Disk S.M.A.R.T Command Failed Error

The main reason for this failure message is HDD failure and when the SMART BIOS feature detects this issue we will see this failure message. SMART stands for Self-Monitoring, Analysis, and Reporting Technology for monitoring the Hard Disk Drive for any kind of malfunctioning. If S.M.A.R.T detect any problems with it,  it will return the failure message.

Solutions for Hard Disk SMART Command Failed Error Message

The permanent solution for this error message is to replace your hard disk with a new one. But there are some other workarounds for this error. They are:

  1. Disable S.M.A.R.T feature in BIOS

    It will avoid the chance of detecting the computer HDD failures and you will not get any more SMART error message. We know it is not a perfect solution for long term.

  2. Disconnect the power and Bus to hard disk and reconnect

  3. Regular Hard Disk recovery methods

    It is recommended to perform any kind of HDD recovery steps like de-fragmentation for fixing the errors of your computer disk.
In my case I just followed the second workaround by disconnecting both BUS and Power cable from HDD and reconnect. It looks a little dirty if you are not cleaning your PC frequently but it outsmarts other two solutions.

Well, that is troublesome...
My hard drive is not even half a year old and I had to buy it after my old one, which wasn't older than a year at the time, broke down. Does S.M.A.R.T. check for temperature as well? I have a habit of leaving the window opened overnight so in the morning it's freezing cold. I know it affects the CP, maybe the hard drive as well?
Alex George said…

It is widely considered as temperature below 25°C can damage HDD. However, the common reason for hard disk failure is the improper shutdown or sudden power off. Make sure you have shut down the computer after your use.

Destination Host Unreachable - Reasons and Solutions

The error message "Destination Host Unreachable " tells that the ping request from our computer cannot find the route to the destination IP address(destination host). It means, the Packet send from your computer reached the destination network successfully but the remote gateway failed to find the destination host. So the remote gateway sends an Echo message Destination host unreachable. One major possibility for this error; there is no route listed in the remote gateway, for the packet send from your computer, to the destination host. If there is no route available, it is impossible to find the destination host and your computer will receive an error message "Destination host unreachable" from remote gateway. So one of the reason for this can be faulty routing table. If the destination host is down at the time the packet send, it may result destination host unreachable error message.
