How to ensure that information is deleted from a failed SSD?

Question

Solid State Drives

Good afternoon!
Everyone knows situations when, for some reason, a disk fails on a server / workstation.
In such a situation, the failed drive must be sent to the vendor for a replacement under warranty.
In the case of an HDD, deleting information from a disk is quite simple - a strong electromagnetic pulse. But this doesn't work with SSDs.
How to ensure that all information is deleted from a failed SSD?
Certainly in a non-destructive way.

Answer 1

No way.
It's impossible.
The only way is to store the information on the SSD encrypted.
Even from a serviceable SSD, it is impossible to completely and reliably delete information, and you are going from a faulty one.

Answer 2

1) Store information in encrypted form, as suggested by Artem.
2) Once, having prepared kebabs, I put a faulty disk on the coals. From what was eventually left of him, I'm pretty sure all information was destroyed. But they won't change it under warranty :)

Answer 3

In the case of an HDD, deleting information from a disk is quite simple - a strong electromagnetic pulse.

Not sure if your statement is correct. Have you tried it in practice? Too strong (high-energy) pulse can lead to the destruction of electronic components, I do not quite understand. In my opinion, it is easier and more reliable to overwrite the entire disk with arbitrary data (maybe several times, taking into account microscopic head positioning errors).

I can't guarantee you anything, try using an x-ray tube. Write a large test file to disk, after exposure compare the checksums (not only crc, but also md5/sha). If successful (checksums differ), repeat so that each flash chip is irradiated.
Another option is to try to connect to each chip with a programmer and actually program the contents. Here, again, there are many nuances, from the type of microcircuit packages to the presence of a malfunction.
