Passmark DiskCheckup run on it, or Speedfan, as Fafhrd mentioned.
What would I be looking for in the Passmark screens?
Click on Configuration and set it to record SMART and warn you with a popup.
Some failure modes can tell you quite a bit, if you research them. For instance, a Reallocated Sector Count failure can quite often be corrected with a full format+CHKDSK, and the drive will be completely healthy and able to be used again.
Thanks. I will have to pass this on to the owner of the laptop as I use mine not his!
