I have a dual boot of Windows 10 and Ubuntu 16.04. Recently I upgraded it to 18.04. As soon as I did it, it started showing DISK IS LIKELY TO FAIL SOON (37° C / 99° F).

I checked the status of my disk via Windows and it shows it’s perfectly healthy. I assumed the error occurred because my partition size of Ubuntu was 64GB (which I now increased to 86GB). Please help me out with this.


Edit: The results of smartctl - attributes smartctl results

    First run sudo apt install smartmontools -y and then edit your question and add the output of this command sudo smartctl --attributes /dev/sda – Ravexina Aug 15 '18 at 10:47

As smartctl output suggests you have "16600" reallocated sectors on your disk, which is really high for the number of bad sectors on a disk.

Reallocated_sctor_ct is a Pre-fail property and its threshold for your device is "30" however your device status indicates a really bad number: "1".

It may not fail right away (or might) however you will definitely lose a lot of data if you keep using it.

Take a backup as soon as it's possible for you, and take the device to warranty if it has any.

  • I have taken a back up already. But is there a fix? Can I replace anything? I do not have a warranty. – Shrisha Bharadwaj Aug 15 '18 at 11:28
  • The only way is to replace this drive – Ravexina Aug 15 '18 at 11:28
  • This drive as in, the HDD? – Shrisha Bharadwaj Aug 15 '18 at 11:31
  • Yep, you have to replace your hard disk. – Ravexina Aug 15 '18 at 11:33
  • Just out of curiosity, will it help if I delete my partition and add ubuntu again? – Shrisha Bharadwaj Aug 15 '18 at 11:35
