Question HDD health suddenly drops to 13%, then returns to 100% health after removing some files ?

[Muz1e]

I've notice this morning that my hard drive drop health from 100% to 13% in just a day. And after backing up some important files and transferring game files to a backup storage and restarted the pc , the health of the said hard drive returned back to a perfect 100%. I am using Hard Disk Sentinel to monitor my storages information. Is the drive already at its end of life? I've used the drive for nearly 7 years already and only used for storing game files and personal files. Never installed an OS on it. Can I still use it to store files on or should I get rid of it?

The drive Info:
Seagate Barracuda ST2000DM008 2TB 3.5" internal hard drive.
12.55TB lifetime writes, 7956 start/stop count (according to HDD Sentinel)

if your hard drive's sudden health drop and subsequent recovery could indicate potential issues. Considering its age and usage, use it for non-critical data or consider replacing it to avoid data loss. and please do regular backups for your data.

Yeah, I have 2-4 different backup storage for my files. I remember seeing bad sector error when I first notice the sudden health drop. But after the reboot, it's health was back to 100%. Is that normal?

That's weird behaviour.
