How to recover HDD? Many bad sectors have grown into a serious problem

Question

Hard disks

Hello!
I recently bought a new mat. board, because of this the computer was outside the case, the cat decided to play with the wires and threw off the hard drive (Seagate ST3500413AS, Firmware JC45). The SATA cable, thanks to the latches, held it (hard drive :)), and the power cable was disconnected. After that, the system stopped booting.
The first thing that came to mind was to check with CHKDSK, I did it through the Live CD. CHKDSK immediately began to swear at damage to the main file table (MFT). I decided to immediately check at startup, from another computer, the same error plus and an error when trying to restore the MFT. I tried to restore via TestDisk, but it also gave an error. Then there were attempts to check, remap, using Victoria, MHDD, HDDRegenerator, but nothing helped. Even another problem appeared, the hard one sometimes began to "turn off" if something accessed bad sectors. For example, Victoria does a scan with a remap, reaches the BADs, skips them, and reads the entire disk in 5 minutes with a speed of 140mb/s. If testing was done through Windows, then the hard drive was marked as Disconnected.
The situation worsened when, after I launched the SeaTools utility, it tried to do a test and told me that everything was very bad on the HDD, here is the warranty code, save all the information. I still think it was a coincidence, but after the reboot, the disk, after each access, began to "think" for a very long time, for 10-15 seconds.
Please do not blame me for leaving the PC in the air, but just tell me how to solve the problem, there are a lot of important files and memorable photos, videos on the disk, I can’t even imagine what to do if I lose it all.
Thanks in advance!

Answer 1

The disk will have to be thrown away.
As for pulling out information, look here (both answers and comments on them).

Answer 2

Now, only data recovery centers are busy with disks for a lot of money if the administrator is an idiot and has not made backups.
the easiest way is to buy a new disk and think about backups.

Answer 3

Try GetDataBack (for NTFS or for FAT), if it does not restore the data, then you can forget about the data or drag it somewhere where it is very expensive and the result is not guaranteed. And the screw is definitely in a landfill.
