Solved Hard Drive health falling now at 100%?

[SinRival]

Not sure if this is the right forum but my hard drive was failing and had a error message saying so yesterday.
I ran a disk check but during stage 5 but laptop had to be turned off because of circumstances. Today I turn my laptop on and everything seems fine. I decide to download HDD Health and it told me that the health was 55% and was falling to 39% and then suddenly few minutes later it's at 100%.

I'm rather confused about this. Can someone help me understand what is going on?

Also another question: Can I backup the windows os to a external hard drive without it erasing the contents on the hard drive? I just want the actual operating system and not any data as I have nothing on it that's important that I haven't already backed up.

You can use the inbuilt backup and restore function to take a system image of your drive which you could then clone to a new drive but this would take everything over including data
There is more reliable software out there for doing this such as macrium reflect or paragon its up to you but with sporadic health results I would backup everything you need asap you can always remove the data later if you need

So doing the backup won't remove any data currently on the external hard drive?

No it will purely take an exact copy of everything on the drive ready to send to a new drive which will then appear identical
