Corsair Survivor GTR 64GB issue

[aynz]

I have a Corsair Survivor GTR 64GB memory stick that has a faulty controller, I have attempted a recovery via PC3K Flash but they don't currently have a XOR for it so it looks like recovery is not possible at this stage.

My client is desperate for the data and I am tempted to purchase and send Ace Labs a working memory stick of the same type so they can create an XOR from it but my question is will a memory stick of the same model have the same controller type as my faulty one or do they change them?

It's a risk to buy a new flash stick of the same model, they change the controller and nands frequently, what is the controller ? have you tried another tools like Soft Centers Flash Extractor?

Hmm, thats what I feared you would say, probably not a good idea to go down that route then.

The controller is IT1168TE-64C 1051-BXO 7511GB, we don't have Soft Centers Flash Extractor, when we plan on purchasing additional hardware we are considering getting it as having two different products covers more issues.

i suggest look in SC forum for such similar cases you might find some juicy info there
that saves ur time n $$$


good luck

Do you have a dump of XORed data? You may want to see this discussion xor-c5f6-128-t20730.html about getting XOR pattern from XORed data alone.

As it relates to the previous post, XOR is to help reduce the raw error rate and eliminate "sticky bits". Some NAND manufactures like Micron implement their own XOR engine inside NAND, other companies like Toshiba don't and leave it up to the controller.

Nice info Jeremy.
