    USB stick data recovery

    Good morning everyone, I'm currently working on doing data recovery on a Patriot Xporter XT Boost 32 GB USB 2.0 Flash Drive, model number:PEF32GUSB. The end of the USB stick was broken when the owner dropped a heavy object on it while it was plugged into the computer tower. I would normally just purchase a replacement of the exact same model and just replace the controller and NAND chips but this USB was discontinued and hard to come by. I'm hoping someone has access to a schematic of this so i can just rebuild the front section with a breadboard. Or if any of you know of any other USB sticks that use the same chipset and configuration that i can do the controller/NAND swap with that would also help me out a bunch.

    I very much doubt you'll find a schematic, photos will help us, maybe note which controller is used.

      Certantly. Attached is the USB in question. Tried to take pictures through my microscope which didn't turn out great but appears the labeling says Phison PS2251-32CF-F UG1007 AKK2M.022

        The damage doesn't look so bad, can't you solder wires from a donor USB jack to the board ?

          That was what i first attempted months ago. There are some missing or misplaced caps that I tried replacing from another usb of a different model and now I have no reference to go off of. Also I believe there may be a short or open on the traces sandwiched inside the pcb. At this point I would rather know for certain where the signals are going than to guess and possibly corrupt the data.

            I did wonder looking at the pads. Is it one of these ? https://www.ebay.com/itm/Patriot-Xpo...B/380925371589

              No I believe that is a different one. https://www.amazon.ca/Patriot-Xporte...ustrec_signin& / https://www.mercari.com/us/item/m683...search_results

                I should also clarify that when i first started doing this, I was attempting freehand with no optics. Now that I have access to a microscope I see a lot of what i missed.

                    That is the 8GB version yes and I do have that one currently. There are obvious differences in the placement of certain caps and resistors on each that I'm uncertain of what their function is. It would be more than just replacing the nand and controller chip. it would be around 8 or so other components being swapped around to make them match

                      I would at least check the resistance between Power pad and Gnd pad, then check the resistance of those MLCC to see if any of them shorted out due to crack when the board got damaged.
