HDD GURU FORUMS

I have been bashing my head against the wall with this one, perhaps the pros will find this question funny, but I have to ask anyways.

To start:

1) This micro sd card should be 64GB. I have not rulled out the possibility of a fake card.

However, after connecting it to PC3K flash it detects the card, and provides this ID:

Code:

Bus= 8 bit/ IO0x-0 ->  ID= 0xADDE14AB  (ID EXT= 0xADDE14AB 424AADDE)R/B OK! - OK! Parts detect... 1 OK! 2 Not Found! 3 Not Found! 4 Not Found!

Does this mean I should have active CE1 and CE2 and CE3 pins to find this extra 3 banks?

If i analyze this chip ID I can understand that it is a:
AD = Hynix
DE = 8GB

Code:

But... if we look at DE bit representation, it means that it can be a 16-bit bus instead of 8?

In my mind that makes sense, because if in a 8 bit bus, one bank is 8GB, 4 banks would be 32GB wich is half of the capacity of the full memory.

Perhaps I'm over complicating this. Can someone shed some light?

IMHO card is fake. Try assembly data and you will see.

Can't do anything on it, i need to figure out why I don't have access to the other 3 banks...

No ECC detected, no XOR, no interleave.
Raw recovery only reports mp3 headers.

So probably new XOR, new ECC, new assembler as most of flash cases now

Thing is, the card is over 4 years old.

Would you be interested in analyzing the dump?

I can look.

I'll upload to ftp later today.

Any idea about other parts or does this chip might only have 1 part?

If chip is fake, probably it have only one bank.

After fast check:
- card is fake
- it use BB
- need new XOR, ECC, new asembler
