I have a Sandisk 2GB with controller 20-99-00128-3 and was wondering if anyone has decrypted one of these? Is it safe to assume that the key is unique for each device and it would be a waste of time to move the NAND to a donor device?

Once i recover data with moving NAND to donor drive

But not sure that it was same controller name

I have recovered several Sandisk devices by switching the NAND onto a working device with same controller name.

This only works with dead devices of course, not ones with degraded memory.

Thank you, I have a good collection of donors and have done this too, many times, but in this case it is a controller that is known to use encryption and I believe the key might be per controller. Was curious if anyone has had success with a swap or with decryption for this controller.
I did just find this post which seems to confirm that the key is in the controller.

what are the symptoms that the controller is dead?

LED flickers 1 time. 2 caps and 2 resistors were blown when I got it. They were replaced with components from a working same device. 24MHz Oscillator was verified. No short to ground now.

I don't know if it will apply in your case since it flickers once, but I just wrapped up my second NAND swap on these for the day. 00136-3 and 00162-2 both fully recovered after NAND+controller swap to donor boards. In my case, they had no signs of life, tested oscillators and good connectors.

So you swapped both NAND and controller to other boards? Interesting. It would be good to know if swapping only the NAND would work to another board where everything else is the same.. to see if encryption is a unique or same key.

I swap just NAND if I have a donor of the same capacity. Only cases I had issues with were from Titanium Sandisks with big size controllers and those that have proprietary NAND chips with Sandisk grid pattern.

it's not unique, done it many times.

Or Key is on NAND.. as there is a strange looking HEX string at the start of these dumps..
Thanks Guys, very useful info
