Hello,
I have this drive that showed 20MB
Soldered a jumper wire for safe mode.
Uploaded recommended loader and created translator. I have access to data.
I need a very big file (aprox 90GB) and opened a DE task to try to copy the list of ranges.
However I get slow reading in most parts (120KBps) and 1.5MBps when it goes fast.
I get bunches of 32 black blocks from time to time ("page marker checking error" (invalid data)). This is what slows a lot the process.
Could this be the loader used?

Also have bad MFT entries in the NTFS partition
I noticed when trying to save the file that it would only copy 1GB stating wrong size

Could memory chips be degraded so fast? Drive is from Jan 2021

That's one and a half year. I'd say it exceeded the usual life span :(
OK, exaggerating, but we've seen chips degrade in a blink of an eye, so...

I think the translator you've built is probably fine.
It's the chips that are in bad condition.
Try heating/freezing, if you're VERY lucky, it might help you.

However, I have to say that getting 90GB intact from a drive in this condition... I'd say chances are close to zero.

Degradation of chips. Try reread many times.

Thank you both for your input!! I will let you know the outcome

Well, situation didnt change either using freeze spray or heating the chips up to 160 degrees celsius
As this is a *.vsddsqlzip file, we can assume it is deeply f*cked

One more thing you could try would be to adjust the NAND Vcc supply in-circuit. Run it through the range from 2.7V to 3.6V.

where is this feature? I cannot find it

That's because it was a suggestion I put forward at the HDD Oracle. The idea is that you intercept the PCB's 3.3V supply and inject your own variable supply.

I assume I would have to cut the trace for that and then inject V

Update so far:
I retrieved the 97GB file but has 0.24% corrupted data, so this one sucked. As it was a compressed file database it couldnt be loaded.
Tried with freeze spray, heating etc... no luck.
Garbage chips.

Anyway there where a few negligences here...
- Server did not have the UPS turned on, and the lights went off
- Corrupted firmware in SSD
- They make the BACKUP of the system from that SSD to THAT SELF SSD in another folder. How stupid is that?
- They make 100GB backups every few days and the memory chips where degraded. Only a year and a half from new.

Remove the inductor and inject the voltage into the load side of the inductor.

Would it be possible to upload a resource dump for this SSD? It would be interesting to see what the defect lists and SMART look like.
