It's a pity you tried yourself. A specialized data recovery company would have done better, and it might be more expensive now than it would have been if you hadn't started yourself.
Anyway, a USB-stick should - exactly like a floppy 15 years ago - be considered as a good means to move data between computers. Not as permanent storage, and certainly not as a good place to store the only copy of some data. So - for everybody following that simple rule - no data is ever lost by a failed drive and there's no need at all for any expensive recovery.
Let's hope you fall in that category.
I dropped it and now there is no LED indicator light lighting up. And it will not show up in My Computer.
I managed to strip it down to this.
So the first thing I notice is that this chip is loose.
And on the underside, it has 4 metal contacts, so we know that it goes there in that missing spot.
However, it could orient either way, and I've tried holding it there myself and plugging it in, but to no avail.
So, now I'm stuck here. I really need to recover this.Thanks.<span id="INSERTION_MARKER">
