[SOLVED] HDD health ?

[Midhun Kumar]

Recently one of my PCs ran into a problem. When I switch on the CPU, the LEDs glow, the fans (the processor fan & the PSU fan, both) function well & the keyboard & mouse receive power from the CPU. But, there's no display even if I wait for long. I took the pc to a local computer repair shop. The person at the repair shop removed my hdd, put it on a hdd case & checked the health of the hdd in his laptop. He showed that my hdd has low health (2%), I looked at the laptop, the software (I don't know what the software was) displayed that the hdd has only 2% health. The person said that I should buy change my HDD, then the CPU would be alright. My questions: what was the software that the person used to check the status of HDDs? What does it mean if the hdd's health is low? What could be the reasons for the low health of hdd? Health of HDD can be increased by using softwares or by running commands like chkdsk, sfc scan?

Unless you can show a screenshot, not really possible to answer.

Did it look like this?

What does it mean if the hdd's health is low? What could be the reasons for the low health of hdd?

Means nothing, if you have no idea, how this software calculates health score.

Probably scam.
Disconnect HDD from your pc and see, if you can boot into BIOS.
If you can't then there's some other issue than HDD.

I don't have screenshot. The mechanic at the repair shop turned his laptop at me & I had just a second to look at the laptop. So I couldn't notice what the software was. My pc couldn't even boot into BIOS. That was why I took my pc to the repair shop. So, it's certain that there was some problem with my hdd. But, I don't what exactly was the issue

Disconnect hdd from your pc.
Can you boot into BIOS after that?

I took my PC to a repair shop. They replaced my HDD with a new one & got it repaired
A new doubt- can PCs boot into BIOS even without a HDD? (I am not a techie in the field of computer electronics, that's why I ask this)

can PCs boot into BIOS even without a HDD?

Yes, obviously.

 

[Midhun Kumar]

Yes, obviously.

Without a HDD, where does the program files for BIOS get stored?

BIOS is stored in BIOS chip on motherboard.
There are no "program files". Just BIOS code.
