HDD GURU FORUMS

I have an 8G Sandisk Flash with the following written on the controller chip:

Sandisk
82-00330-3
9243-PMR107
8DC1

I have checked PC3000 controller database but, I can not find a controller resembling the above numbers.
I have also been googling the net but in vain, I fail to get any controller related to the above numbers. Can someone please shade a light on this.

Thanks

Did you contact ACE tech support for remote assistance?

It could be new controller. I have never meet this model. PC3000 usually do not support Sandisk controller. Try Flash Extractor.

could you post pics of the exploded device and closeups of both sides of PCB?

probably more useful to read the NAND, and then see if the controller matches a config from another one. Some of the Sandisks are encrypted, hope it isn't the case.

I can have a look If you want to upload the dumps of the nands.

I may have a controller like that, I can check, and if so might be able to figure out XOR and mix by comparing with my good one.

The information on te NAND is:

P12370092
SDTNNMBHSM-008G
WSB526001855

Here I have attached pictures of the top and bottom sides of the PCB.

Thanks for any info.

I ave not yet succeeded in taking a dump as I still do not have the necessary information to get the NAND identified.

Did you try and read the NAND, if so what is the Chip ID? 45 CE 95 32 ? should be a 16-bit chip 8640 page size with 1 8GB Bank. Cant see a problem with reading it

I have not yet been able to identify the chip; I sall ceck if I have some physical problem with the chip.

What equipment are you using, does it have a physical jumper or different shield/adapter for 16bit chips maybe? It is possible for the chip to be bad, though rare in my experience

I am using PC3000 Flash. I can read other memory chips without any problem.

Does this help?

Your NAND chips appear to differ from the following "standard" pinout:

For example, there are several NC pins which connect to the controller, plus there are several additional supply pins.

Thanks franc, exactly what I was talking about
