Hello,

I'm trying to recover the contains of a defect UFD.
I can't find the correct pinout.
Here is a picture after coating has been removed.

Someone ever processed this kind of flash drive?

Thanks
MIke

Hello,

Yes it is. Pinout 179 but the site says they don't share pinout and sending them the flash drive is not an option.

One option is to buy a logical analyzer. If you create waves i can help decoding them and prepare the pinout. Other option is to give the UFD back to client and send to someone who has the pinout or can discover it.
I don't think that there's anyone who shares/ sells pinouts except me :mrgreen: Sadly i don't have this one.

Hello,

We have a logical analyzer.
We were planning to use the autodetect feature of PC3000 to try and find the pinout but any help would be appreciated.

Have a nice day
Thanks
Mike

Don't experiment on clients device. I doubt that autodetect will help you. If it works at all.
Solder all unique pins, create waveform and analyze or send it. Or, best option, get the same device for pinout discovery.

It is not exactly v179, but yes, very similar. Now pinout is the simplest part of flash recovery. As you can see at UFD v179 description, there is high probablility that flash use FC1178/FC1179 controller which is very complicated to recover. Next challenge will be problem with correct reading, bad bits, cut pages, assembler, and rebuilding file system. Here you can find some sample of solution: http://flash-extractor.com/library/FC/F ... 98_b3__1x1 Last time I have 1800 bad bits to cut from FC case...

PS. I share more than 500 solutions models for FE for free already, VNR resources created by me - ECC and XOR is share for free (~50% of all avaiable), read retry algorithms implemented at FE, monolith database is for free to help everyone (for example not waste time on LDPC cases since we not find solution). I can't share everything for free, I need pay taxes and sometimes I must eat ;)

The development of the Monolith UFD Pinout solution is progressing smoothly. It is expected that it will be released to end users in half a year. :wink:
