    Hey guys.
    I accidently broke my girlfriends netbook and she is doing my head in about getting her pictures offs of it.
    It's one of those internal flash memory things with a small ribbon cable on it (see pic).
    Can anyone help me out on how to connect it to a pc?

    How did you break the netbook? Depending upon what was done then restoring that to some kind of working capacity, at least long enough to get things off, is possibly the better bet. This does also include buying a "dead" version of the same model or similar one from the usual places and using that. If it was a screen broken then hopefully it has a HDMI out or something you can force it through, if you broke the keyboard then get a USB keyboard... apologies if I am stating the obvious but I have to mention it.
    Equally I have seen many of these things using NAND memory have encrypted which makes this fun.

    If we have to dip a toe into big boy data recovery then that looks like a single chip (I imagine you would have said if there were more paralleled up or hidden behind something). That looks a bit large for a basic breakout board, especially for something as packed as a netbook, but who knows what reference design was being used.
    Here is the datasheet for the chip资料.pdf

    Looks to be fairly standard flash and no mention of onboard AES crypto or anything like that. You also have a nice ribbon to play with (those other little parts are probably just basic pullup/pulldown resistors and smoothing capacitors or something, might want to account for them at some level but it is not a controller on top of everything). If you still have the rest of the board and are going to cannibalise it then might also want to get the socket for the ribbon.

    NAND memory can be read in many ways, the "not much money" method is that the XD memory format is actually raw NAND; it is why all those console hacks can use XD cards to replace NAND, however it cuts the other way and you can hopefully buy a cheapo XD reader (or multi reader with XD), wire it up and hopefully it mounts directly but if not then you can probably image it. It will not be terribly fast but it is only a few gigs so it is not that bad.
    Otherwise yeah you are doing it properly and sorting a NAND reading setup, fortunately it looks like you have the surface mount package for this one (the same product line has a customish LGA which would have been fun to try to sort). Hopefully you are good at soldering (I would really want hot air at least and possibly even some IR soldering, don't think drag soldering is going to cut it here).

    n.c. in this case means not connected/no connection which is nice (you can see it on that chip as well with that whole run just sitting there). w.e means write enable which you might not need (do it if you can or do not want to mess with Linux -- if you have to overwrite windows permissions or take ownership then it would help). Ultimately this means you then only have 19 pins to worry about at most, and might be able to drop that further. Do note that it says "Connect all VCC and VSS pins of each device to common power supply outputs. Do not leave VCC or VSS disconnected.".

    My vote is try to find or borrow a suitable version of the dead netbook and use that. They tend not to go for the most money and unless you are familiar with electronics it would less aggravation in the long run, indeed I have most of the gear here to go manual if I had to and I would still try to source a donor netbook for my own personal data recovery, let alone a client's that would also be facing a several hour electronics repair job.

    WOW. Like srsly WOW.
    That was without a doubt the most concise, thought through and informative answer I have ever got in my entire life.
    You obviously put a good amount of time and effort into that and I'm extremely gratefull.
    I think your suggestion about getting abother netbook will be the easiest for me to do. My soldering is not the best.

    Again thank you for your reply.
    If your ever in Hampshire I will buy you a beer.
