Sandisk 82-00258

[dmarques]

Hi,

Has anyone had flash with this Processor: 82-00258.
Basically, just want to know if it's encrypted?

Thanks

not sure about this myself, but I found this on another thread:

Not come across that particular chip, but 20-82-00253-2 isn't encrypted (well, apart from XOR)

Hope its useful.

Hi,

Yep, I saw that thread also, but wanted to be sure about this one.

Thanks

search FE site as this chip is apparently 8bit using a 16bit pinout.

I might be wrong, but this one does not appear on SC site.

[Cleanroom]

definitely a 16bit pin out

I cannot find anything in my notes about the controller

How old is the device?

Pretty much anything that had U3 on the casing is encrypted

I know it is a pain... but you may want to just remove the chip and read it in. that will give you a 100% answer.

and resolder the chip when you are done.

What is the issue with it. If it is a power issue I may have a solution for it. Needs a good pic of the front and back tho.

I think you might be too, well kind of..

Although it isn't in the Library, search for it in the search box in upper right. Provides info that would possibly be useful to you. It looks like you need at least v2.35 of the Nand_Reader software.

If you do not have a NAND Reader, possibly get someone to read it for you, or I would be happy to if you want.

BTW, Id be interested to know what ID you get?

I might have a drive with same chip, I will look through my research drives.

Re-Encryption. Im guessing the reason for encryption is the U3 system allows users to have apps and docs and maybe more of a reason to encrypt because of say stored passwords in portable versions of firefox or email etc.

I remember (vaguely) something about some higher security drives and the methods to get a password. basically I think the gist of it was that when the drive checked the password, you could view it in RAM.

I dont know if the password was stored on flash in the controller or on NAND though, so depending on how functional the drive is, you may be able to get the password, or it maybe stored on the NAND, and there is probably some haker that has written it up or something similar.

Kind of thinking out loud here, so YMMV.

I love tackling this kind of thing

Good Luck,

Cheers
