Can the HDD be recovered?

Question

Programming

I fell into the hands of a "killed" disk, bads all over the disk, brake freezes, etc. I decided to mock him, wrote a utility that fills the entire disk with a template, which was a regular file, after which it checks how the file was written via md5, the interesting thing is that after 2 - 3 runs by the utility all over the disk, all bad sectors have disappeared and the disk works like new , in connection with which the question is, could the disk be "healed"? And will the problems come out later? The reason why the disk began to blunt is unknown, most likely the laptop was "kicked" during operation.

Answer 1

You need to look at SMART, if everything is fine with the disk now, then either the bad sectors have been reassigned and the Reallocated Sector Count value has increased. If he did not grow up, then you had so-called. "soft bad" that occur due to poor power supply, cables, etc. And after rewriting the checksum of the sector was recalculated and it turned out to be normal.

Answer 2

Once they brought a laptop with a problematic (it seems to be hit) HDD. I put in a new disk, gave away the laptop, they left the old one for me as a souvenir.
Decided to play too. A check by Victoria showed that on the surface, in the range of approximately 40 to 50%, there is a sea of ​​bad blocks subject to Remap (replacement from the reserve). The reserve was not enough to treat everything.
I put the disk in the USB pocket, broke it into 2 parts - from the beginning to 40%, from 50% to the end. It has been working for several years without problems as a mobile storage for non-critical files - movies, music. software, etc.
So - check the surface with Victoria, and everything will become clear.

Answer 3

It's just that the controller marked the blocks as bad and replaced them with spare ones at the end of the disk, in general, the fate of the disk is to die if this happens.

Answer 4

problems with the disk are already guaranteed and this kind of "treatment" will not fix them

Answer 5

physical or prog errors?
