Good afternoon. I received a 1TB SanDisk Extreme Portable SSD with a lot of important data on it from a customer who mistakenly formatted it in exFAT. He wasn't sure how it was formatted originally but he said it was for Windows so I am guessing it was either NTFS or exFAT. A raw recovery in R-Studio, PC3K, and Disk Drill gives nothing but a few useless files. He doesn't think it was encrypted before. He said the format took only a few seconds. 

Could TRIM cause something like this? If not, the only other thing I can think of is encryption. Am I missing something?

Thanks.

Are you not able to see the sectors and determine if they are returning zeroes vs garbled data?

It does appear that it is almost all 0s on the drive. Is the only explanation that the entire drive got formatted?

TRIM process runs in background when  the drive is IDLE

as explained it in many places 

after an n inizialization or delete command , the longer the drive remain Active , the bigger it becomes the Real erasure of cells 

and anyway the unique possibility is the creation of a virtual translator from a previous copy of the translator 

this mean that it the drive is not supported by PC 3000 you anyway won't find anything more that what you have already found

How are you testing? 
Disassembled with the internal NVMe alone?

Or through the SanDisk controller board that the NVMe SSD is connected to internally?

IMHO It's not TRIM. TRIM leaves all/most of the MFT records in place. So a scan will find files via the MFT, but the files show all zeros. A full format wipes the drive, so shows all zeros.

SanDisk Extreme USB in addition require di USB adapter 

because such adapter is transparently encripting the drive, like it happen with WD USB drives
