Hello,


mentioned drive is not detected by OS.
What to check on PCB

Need picture of both sides. Most obvious thing to check is the fuse in the corner next to the connector.

additionaly to the fuse, under a microscope or magnifying glass, check the usb headers pins for breaks in the solder or trace. Also commonly the BGA / LGA chips lift pads off the PCB. you can sometimes see this turning it on its side and looking with light and microscope/magnifying glass.

if nothing obvious, a good DR firm should be able to read the nand chip and recover files. I can do this for you if you would post to AU.
regards

PS, please crop the background out of the image! When doing this it took picture from 1.1MB to 313kb

Thank you Jar and HaQue for replays.

Here is another picture.

extremely hard to tell from the picture angle. is the controller pins closest to the nand chip soldered down properly?

remember the bit about cropping the picture? an easy way is to open in paint, select all, drag picture to top left. then go to the bottom, "grab" the canvas control and lift up, reducing the size of the background, and do the same from the right edge. takes 20 seconds, does not reduce the size of the actual subject of the picture and reduces loading times when maximising picture. Just a friendly hint so you can help the people a little that are helping you.

but anyway, I don't think any picture will help unless it is a very good and clear one, most of the issues that you would visually see are only visible under careful scrutiny using a microscope, and even then quite difficult to see.

Does anything at all happen when you plug it in?any windows beep, any "you need to format" message?

you can try CAREFULLY using tweezers to bridge over the fuse or resistor that is closest to the usb header, it is labelled F1 (1R5). if it comes to life, permenantly bridge it with a solder blob, recover data and snap the little biatch in two

I would touch up the solder on the USB connector pins to see if it helps at all. They look suspect: http://prntscr.com/8yla3r

Agree with LarrySabo.

If that doesn't resolve the problem, then measure the voltage drop across "F1". It is actually a 1.5 ohm resistor, so this should tell you the current draw.

Also measure the voltage across the capacitors. You should find +3.3V or perhaps +1.8V.

The crystal (Y1) would be the next suspect.
