So, I was angry at my laptop (Lenovo Y570) for updating at the wrong time and taking all the bandwidth and I hit it a couple of times on the front side, beside the trackpad. The laptop then froze, so I force restarted it, but when it attempted to boot it just said "a disk read error occurred press ctrl+alt+del to restart". Restarting doesn't help. Now, I have dual boot (on the same hard drive) on that PC (Hackintosh), so I booted that and it worked just fine for about half an hour. Then it stared lagging and it became unresponsive. Later attempts to boot it up again were unsuccesfull. It did start to load it, but everything was SUPER slow and it got stuck halfway. Meanwhile, Windows 10 still just says "a disk read error occurred press ctrl+alt+del to restart". I even made bootable USB drive for Win 10, but it doesn't load it. It starts, but it doesn't load, beacuse something made my computer 100x slower.
Any ideas?

I aldready tested RAM with Memtest86+. I did 2 full cycles and it passed every time. I never tested it before, so I don't know of this is normal, but it was testing good 2 hours per cycle.
I also opened my laptop and took out the hard drive and pit it back in. No visual damages.

uh...why'd you hit it? You know how people say don't drop a hard drive when it's running? Shock is not good for the system when you have a reader hovering very close to a fast spinning disk...

It's very possible that you caused a head crash, where the HDD reader makes contact with the spinning platter and causes permanent nonrecoverable damage.

Hi there Daviid5,

Looks like you've damaged the drive. I hope you've backed up your data while the laptop was still running good.
Don't expect to see any damage on the outside of the drive.

One thing you can do is to take it out of the laptop, attach it as a secondary drive to another computer and test it with some of these: http://www.tomshardware.co.uk/forum/282651-32-best-diagnostic-testing-utility

Ok, so I replaced my HDD with one from my old laptop and everything works now. So it looks like sonething actually broke in my HDD.
Is there any chance I could get my data from the broken HDD ( I didn't make a backup :( )

Attach it externally to another laptop with SATA to USB adapter. (or internally to a desktop machine with SATA and power cables)

See if the drive gets recognized. In case it does, you can try to access it right away and try to get your data.
In case it does not, you can go to Disk Management and see how it is recognized over there. You can see if you will be able to access it with some of these tools: https://www.lifewire.com/free-data-recovery-software-tools-2622893
