Computer techy people

the hard drive errors mean the hard drive is having mechanical issues and is in the process of failing.

think of the errors like an old man having chest pains when he runs up the stairs

it means he's going to have a heart attack - and you can't know in advance exactly when it's going to happen.

same thing with your hard drive - it's telling you it's about to fail so a factory restore won't fix it.

hard drives fail at the rate of about 10% per year - so if you have 5 years on the drive you're about average - if it is older you're on borrowed time.

hard drives are pretty cheap - if you can afford a solid state one it will speed up your computer because they read/write faster than the mechanical ones do.

Ask your tech friends to do a full format of the drive. And reinstall windows if you have everything backed up.

It’s the only foolproof way to sort out your issues provided it’s not physically failing.

The reliability can be determined by the current size. As sectors become unusable and the g-list is expended, the available size begins to reduce. This can give you a dipstick measurement of how long you have.

if you do get a new hard drive, I would recommend a solid state drive

Yeah if it's a mechanical error you can usually hear weird clicking or sounds you generally didn't hear from your computer before, then yeah TBH it's fecked and it's not worth saving if you got the data you need backed up already but if it's the machines OS that's got buggy and packed out then sure hit the factory reset button. I mean it won't do any harm either way you can hit the reset button for nothing but I suspect with your friend saying you need a new one it's a mechanical error with the harddrive itself either way not worth investing too much effort into particularly if you have everything you need off it already.

Was it working well before?

You need to get a new one ASAP. If you can retrieve data off the old one then do that as it will liikely fail completely - although if all your information is on cloud then you shouldn't lose anything - but make sure it all is on cloud (just in case you have stuff in your Documents folder or perhaps pictures etc.

How long did you had it?

This is a complicated one. You're going to have to switch your PC off then on again and while it's loading, do a hand stand for about 3 seconds, than back on your feet, do 4 on the spot back flips, dance like witch, pour yoghurt on your keyboard and yell U.S.A 5 times.

if your hard drive is "having errors" as in sectors of it have gone you need to replace it ASAP. SSDs are super cheap now so it wouldn't be a huge expense.

The hard drive is failing.
You'll will need a new hard drive, backup what you can and get a new one.

A small suggestion, I'd recommend also getting an SSD for your operating system. Hard drives are slow. Even if it's just for your OS your experience will be vastly improved.

You should stop watching porn lol
