Is the hdd good or not?

Question

Hard disks

Good evening.
Help me to understand.
Here is an incomplete list of problems:
1) There are freezes of browsers, especially mozilla, they open for a long time, with difficulty, although there are only 4-5 tabs, mostly forums. As soon as I start it, everything seems to be fine, after a while it starts hanging. It is difficult to open new tabs or close old ones, page scrolling slows down.
2) Skype hangs, I restart - everything is fine. At startup, the program window sometimes appears with "pauses", it seems that during the launch process a pause is set for a couple of seconds, then the download continues.
3) When I start nautilus - it can take a long time to load, when moving files it can close or freeze.
4) When the browser is running, the cooler starts to spin furiously.
5) Calling the context menu slows down, in any program.
6) When viewing the system boot in the "system monitor", the paging file is used on a par with memory. For example, 2.5 GB of memory is used, the same amount of swap or a little less. I close all programs, but the paging file usage does not decrease to "0", again, it uses the same amount as the memory (for example, 750 mb -> 700 mb). It is set to zero only after an overload.
I checked the memory with memtest + 86, no errors.
Checked hdd victoria and mhdd from DOS. The disk was not formatted, checked with the installed system and files.
If you reinstall the system, then for a while there are no problems, then gradually I begin to accumulate.

Answer 1

I looked at the screenshot from Victoria - the disk is definitely broken. In a healthy disk, all sectors should be with an access time of 5 and (partially) 20 ms. 50 ms are allowed, but undesirable, and the presence of sectors with a longer time indicates that the disk has begun to crumble, and the information from it must be urgently backed up. And you have 200 there, and 500, and even just found an unreadable one. What is there to be surprised about the brakes?

Answer 2

This is an age-old problem of lenovo, their drives are complete crap. And in general, for some reason, everyone likes to save on such things. Option two, swallow and change the disk or for a guarantee and return the money. Service centers repair very reluctantly, so 99% will be a refund.
As for the disk, yes. He is defective. This is evidenced by read delays exceeding all norms (this is when the chipset, in the hope, reduces the rotation speed to a minimum at the 10th iteration) and appearing read errors. While the stage is not terminal - save all the data.
Advice, do not skimp on a clean ssd and in no case look in the direction of hybrids, that's still rubbish.

Answer 3

What a cute nonsense in the answers.
-----
Essentially:
1. The screw is quite normal. It doesn't make much sense to focus on squares on modern disks. The only thing that is, is 1 sector is trying to be reassigned in the 197 smart parameter. Which is ok for his age.
2. To avoid brakes, install an SSD.
3. Well, specifics are needed. Look at least the 3rd line of top, in what states the processor is most often.
