HDD is dead after less than 120 days. Suspect if this is even a legit hard drive, or a fake. It may be legit and just bad. Windows shows it has over 150GB of free space, but chkdsk reports "Disk does not have enough free space to replace bad clusters". Replaced with a legit SSD and rebuilding the machine for my poor old man so he doesn't have to go long without a machine. SSD was double-sided sticky-taped in the machine; not the biggest deal, but also not ideal.
