Question Hard disk health dropped after hard reboot

[esvada]

So I was doing file transfer to from my computer to my external hard disk this morning and aside from doing that I was also opening up 3 instances of BlueStacks and then what happened is my computer freezed up and with no control over it I decided to do hard reboot by holding the power button. When I restarted I checked CrystaldiskInfo and Hard disk Sentinel said this on the menu:

I'm confused on what to do now, this is the first time I messed up this bad. That's why I figured to go this forum and ask you guys for opinion on what to do first and step by step after this happened

Immediately back up your data and obtain a new drive. This one is failing and could go full dead at any moment. There's no repairing a drive in this condition.
