Hello,

I have a µSD case. The pinout is PC3000 "micro SD de type 2" and I managed to solder the µSD to the soft center wire adapter.
The chid IDed 95D586A5 so I read it with the 95D585A5 config.
What bother me is that in the 2112 bytes page, the datas are organised like that :
512 data + 20 ??? + 512 data + 20 ??? + 512 data + 20 ??? + 512 data + 4 block number??

What do you thing ? Have you ever seen something like that ?

hi,
you no need make config for this case. it's 2Gb? it should has config in software. you did something wrong on connection. double check it only.

The Chip ID doesnt look right to me.. What does it say the chip number is? and what is the card, brand, size etc, and do you have a photo of front and back?

cheers

Probably you make a mistake. Check your wires, maybe you swap some data channels.

First, thank you for your answers.

An update on this case since my first post...
I rewired/soldered evething twice and I still got the same result. So I don't think the ID problem is related to my wirering.

I finally got some pictures. So what I did :
- Read the chip with the 95D585A5 config (despite the 95D586A5 ID)
- Use the page format described in my first post
- Export the dump without SI and without sectors full of 0xFF
- Give the dump to Adroit Photo Forensics 2013

So for now, since it's a free case (for a co-worker), it's closed.
Maybe i'll get back to it in a couple weeks/months to try to get a full filesystem and not only pictures.

Thanks again for your answers.

You probably know this, but if you can get the datasheet for the chip, it should have a breakdown of what the Chip ID means. I havent looked at it for a while but each bit in the ID means something.

The Chip ID is interesting, could you possibly post a picture, or say the chip manufacturer and Part number please?

cheers

Here are the pictures :

100% sure it wrong ID. It may internal problem if you confirm connection correct. I can do deep analyze for such case.

I was going to say the same thing.

Btw, all the Kingston MicroSD cards Ive seen have the Kingston brand on them. Is it possible this is a fake?

I remember reading a writeup of a well known hardware hacker, bunnie, that investigated fake cards, went into quite some depth. It may or may not be the case here, but interesting anyway to read http://www.bunniestudios.com/blog/?p=918

also, when I mentioned the datasheet, yes I did miss that it was a MicroSD and not a TSOP48!

you need change page size to 2144. last sector bigger then 532. it contain ecc and markers. it is kingston card.
some nand chip used only in mSD and difficult find datasheet, if you see page filled all with data try change page to bigger.

I'm not giving up so a quick update :
The µSD was resolder again (not by me but by a coworker) and I still have the same ID and same dump... So same not so good result in the end.

I found that on the Ace Lab help (http://www.pc3000flash.com/eng/help/hel ... d_read.htm)
So I'm starting to think that the ID could be right.

I tried that and the result is that every byte afer 2112 is the same as the 2112 one so i'm guessing 2112 was the correct page size.

I'm still not giving up...
