Another extremely weird behavior I noticed, after deleting the partition, it now goes back and fourth from no partition to having an partition, but not formatted. Its definitely beyond repair.

Heres something interesting I found after using validrive. It looks like it only validated 16kb of storage space. Maybe the controller died?

ValiDrive is extremely clumsy as is demonstrated by its report. Just another of SG's f*ckups

The graph does not at all support the conclusion.

But that tool would work on confirming chinesium drive sizes?
And forgot to mention the drive went corrupt after being dropped from my desk (it was from around 80 centimeters). I guess the problem will be the controller or the flash itself (its unbranded with "HVNE4F4 1025" written on it).

Try cloning the drive with DMDE, then run R-Studio or Rundelete on the clone. If you're still getting corruption, cooling the NAND chip with freeze spray or measuring its voltage might help.

But whats the point of running R-studio on the cloned image? I couldn't find any options to repair corrupted files under rstudio and rundelete. Already measured the voltages for controller and NAND and tried freezing, cooling with compressor and putting a gpu heatsink with a fan on the NAND with less corrupted files, but still corrupted nonetheless.
