55700 hours or the grey old age of a SATA drive
Friday - Jul 7th 2017 - by - (0 comments)

A few days ago I wrote about a problem where I could not boot Linux Mint 18.1 after running apt-get upgrade. It turned out to be a problem of a dying hard drive.

The SMART output of this drive is quite impressive, especially the power on hours:

Yes, this drive ran for 55'700 hours. Although a lot of defect sectors (and read errors) were detected, I was still able to copy the whole Linux Mint 18.1 installation to a new hard drive (only one file was not able to be copied due to read errors).
