USB Memory Stick Not Recognised

I have a USB memory stick that has stopped working. I can plug it into any computer but after apparently installing as normal it then says USB DEVICE NOT RECOGNISED. It doesn't show up at all.

Is there anything I can do to recover the data using any of the commonly available tools or is this a candidate for the likes of specialists like ON-Track?

Same has happened to me on different occasions. Some times, if you take the USB out and plug back in to another USB port of same computer, it works; otherwise, switch off and reboot the computer, it might work. If you use on a different computer, it might work.
If none works, go for the above options.

You may try with knoppix ( Download the iso, burn it, restart the computer with the cdrom in (boot from cd).
Then when knoppix desktop is available, plug the stick in.
You may see if there is some errors with dmesg (go in the console and tipe dmesg). You may then copy it to a fat partition (not ntfs), or to another stick.
It seems complicate, but it is the best way to see what is wrong with your usb stick.

if the connections are loose solder it back together...

But you did not specify enough : "after apparently installing as normal   "  what happens? sound signal ?
do you see it in device manager or not?
You can try Getdataback or Stellar - if they manage to see the drive :,collid,1295,00.asp            Free Recovery                  pc Inspector                                    GetDataBack                                    Stellar                              RecoverMyFiles                                    Restorer 2000                  Easy Recovery

The stick installs ok. I get a message from Windows saying this but shortly after another message says the USB device wasn't recognised. I have tried all the other suggestions bar the soldering suggestion, without success. It looks like the drive is done for. However, the suggestions will come in handy in future so I would like to share the points out...

did you try formatting it? maybe it works

Couldn't format it as it wasn't there to format...

thanks, I am surprised the soldering didn't take care of it... I have had multiple drives get screwed up from pocketing them and the connections loosen up...
Good luck with it next time.
