HDD failure

[traso]

I just had an issue with my HDD i will try to explain as detailed as possible, i'm using win7
Recently I decided to clean my PC so I bought a can of compresed air, unplugged my pc ad cleaned it when i wanted to pull my HDD i felt a crack, probably the PCB and stopped then i inspected it but found nothing, I pulled it again very gently this time without feeling anything and cleaned it, then I connected everything again and booted the PC, it took about a second to recognize the components but it booted just fine, I made my homework watched some youtube videos and turned it off

I did it again the next day, this time it booted just like always without issue and worked just fine the 4 hours I used it

The next day I booted it again without issue and did my work, then I started messing with blender files extracting images to get HDRIs and materials, I worked with sbout 4 files and then one of about 500MB it took a while to open but i didnt give it importance, I made what I needed and closed the file without issue when I tried to open the next wich is about 300MB the program froze but i thought it may be stuck opening the file and gave it time but after about 3 minutes I decided to kill the process, task manager didnt show this time with Ctrl + Shift + TAB so I tried Ctrl + Alt + supr and it didnt work either, the whole system was unresponsive and after about a minute task manager finally showed up so I killed blender without issue but the system was still unresponsive  
I decided to reboot the system and it showed at startup HDD inminent failure with options to enter the BIOS or boot from somewhere else, I booted anyways and it worked but the system was slowish, I downloaded an HDD testing tool and ran it, it showed my HDD was damaged probably by bad sectors, I shut the system again and buy a brand new 2TB HDD (the other is 1TB) and cloned the drive right away, the new drive boots just fine without any warning message but considerably slower than usual and the system is slightly unresponsive, I downloaded seatools (both HDDs are from seagate) and made the long drive test on the first drive, after about 3 hours later it got stuck at 82% and I decided to cancel it after 1 hour of being stuck and I also made the short test in the sexond drive, the software said it was also faulty but windows doesnt say anything (it had constant pop ups saying there were problems with the HDD with the other drive) nor the boot screen
currently my PC refuses to boot from the first drive (missing drive or drive error) and it boots without any error message but slowly from the second drive, I made a bootable DVD with seatools for DOS but i doesn't detect any drive (even other drives i have lying around that work just fine).
what should I do?

Id do a reinstall, if the old drive was bad, it probably messed up some files.

 

Also get a ssd, it will be much faster, and there not that much more now.

How did you reboot the system if it was not responding, did you press down the power button (this is definitely not a good idea as it would likely cause data errors on the hard drive or related problems) What brand of hard drive do you have, I think that the drive is about to fail most likely because you mentioned the slow speeds and from there I would recommend to stop using the drive and send it to a data recovery/drive repair facility or replace the drive if you are satisfied with getting your data off of it?

I did a regular reboot without pressing the button and as I mentiones both drives are from seagate

I will try this, currently SSD are considerably more expensive where I live and faster load times isn't something I really need in my case
