Revive SSD

Question

Iron

I had a 32 GB SSD, Adata. The system stood on it and in two years shuffled it to the point that everything started to collapse (a week of life on a crumbling SSD is an interesting experience, I can share, it was funny). I changed the disk, but the old SSD remained. It is now Read Only.

How would it be formatted now so that the worn-out sectors are no longer in circulation at all. At least half of its volume should be in 100% condition, because it contained static data.

Answer 1

Actually, you are the happy owner of the “correctly” deceased SSD. When the critical wear of the NAND Flash cells is reached, the controller switches to Read Only mode to be able to save the data. There is no way back. I have more than 20 SSDs on my hands and three of them died “not right”, i.e. not defined at all. Now I know that there are "correct" ones.

Answer 2

> At least half of its volume should be in 100% condition, because it contained static data.
For a system, SSD provides only an abstraction of LBA, and it calmly shuffles worn out and not worn out cells into a simple one. So they are all worn out.
And be sure to tell us the experience of a dying SSD, this is a rarity, such an exemplary death.

Answer 3

Why half? The controller itself must mix the cells for their uniform wear, so it should not play a role - static data or dynamic. If he died, then he must then die all

Answer 4

Those sectors that you think are not worn out could easily be used by the controller. The exact algorithm for choosing a block for replacement is unknown, the controller could, in theory, shift static data, including to more worn blocks, and write the next portion of data to less worn ones. Based, for example, on the frequency of calls. Because static data is rarely overwritten, it can be on a more worn block, etc.
You can only advise to update the firmware to the current one or look for diagnostic software.
