Re: [PLUG] Flash drive "No medium found"

Thanks for the thoughts.

I did glance at eBay but I haven't really trusted anything on there in years.

I doubt it's cracked solder, the chip is tiny and very integrated. If I can get it out I'll certainly look and try the heat/solder gun ideas if appropriate.

I'd love to swap in better guts, the key (ha ha) is that the chip is small and flat, like I said at bottom, 11 x 23 x 1.5mm so any clues where to find a chip like that appreciated. Best pics I could find at bottom.

With a drop being involved, and the data not being important, you might
be able to reflow the connections with a heat gun and get it working
again, but IMO USB flash entered the "disposable, replace instead of
fix" realm a few years ago.

    Along the same thought as Rich, if you get the thing open, mayhaps
    it is just a loose component if you have steady hands, a sharp iron
    tip and some fine solder you might be right back in business.

        As someone who has done what I suggest, if you go as far as
        prying open the plastic, I'd swap out for different/better guts.
        One of my old favorite USB keys is built into a decent pen, and
        it's been 64MB, 256MB, 1GB, 4GB, and now 16GB over the years.
        Just need to find a replacement with same size or smaller PCB.

                        4GB USB 2.0 Flash Drive [1],
                        but someone knocked a computer over at school
                        when he was using it and now
                        it doesn't work.


                    My theory is that the flash memory is damaged, but
                    the flash memory
                    controller is not.


                Thanks Mike, that was a good idea for testing.  Unless
                someone else comes up with something brilliant, it looks
                like it's toast.  And I can't find a replacement anywhere.

                The chip itself looks to be 11 x 23 x 1.5mm when I
                measure it and the best images I've found are
                If I got something like that I might be able to prey
                open the plastic part and just swap the chips.  Ideas there?
