A friend of mine brought me her USB flash drive that had ALL of her school work on it from the past 3 semesters...most importantly everything she has done so far this semester. When you plug it in it says "Not Recognized" and I don't really know what to try next. I have tried multiple computers and it is definitely an issue with the flash drive and not the USB ports on the computers. The drive itself doesn't matter, but we really need to find a way to pull her documents off the drive. Any and all help is greatly appreciated.

It is a Sandisk 2GB. She was using it on her office PC, which is a Core i5 machine with 2GB of RAM running Windows XP. I have tried it on 4 other computers (2 running XP, 2 running Windows 7) but it still doesn't recognize it. The computer recognizes that something has been plugged in but it does not show up in Disk management or My Computer. Yes, this is a USB thumb drive.

The next question is are all of the computers the same versions , 32bit or 64bit? Sorry for all the questions but when there is no direct contact the only info is what is posted so to make a determination all the facts have to be known. There is one more thing and that is when the drive was removed from the office computer was the safely remove drive option used?

I am not sure if the safely remove option was used before it broke, but now it isn't even an option.

If the flash drive was written by a 64bit computer then the drive will not be recognized by the 32bit computers. Does the drive work in the office computer where I guessing it was used? Or is that why she brought the drive to you in the first place?Umm...thats not true. My office machine runs 64bit Windows 7 and I have NEVER had a problem with a flash drive not working in 32 bit computers. No, it does not work in the office computer where it was used (32 bit Windows XP), yes, that is why it was brought to me in the first place.

It is for sure that something has happened to this flash drive either it's defective or something changed the condition of the drive but clearly the computers ackknowledge that something is connected when the drive is pluged in. I'm not certian that this can help but if the partition in the drive has been altered then you may be able to get the data off with this free software.

With the fact that there is important files on it I wouldn't give up on it just yet , there has to be a way to get those files off the usb stick.I took it apart and it turned out that the connections were just loose. I managed to hold the connections together long enough to copy everything over.

That's good that you were able to fix the flash drive yourself.
Just to attempt to post diagnose the drive - the broken/bent connections disconnected power so the drive was never being turned on. The PC was still able to recognize a usb device was plugged in by means of the pull-up resistor on the D+/D- lines (hardware) of the flash drive.
The flash drive was not able to be enumerated (as it wasn't being properly powered), which is why it did not show up in Disk Management or My Computer.
Luckily you were able to fix the drive yourself and pull the data off the drive. If however you couldn't, there is always the option of using a flash drive data recovery company

I thought that I have already posted my reply, but I see that I have not because of the member sign up process. The solution to your problem is very simple...very simple indeed!
The reason why your USB flash drive is not recognized is because the USB flash drive has been previously encrypted on another device. In essence, the USB flash drive has been password protected and then some. You must insert the flash drive in the device in which it was encrypted, enter your encryption password, and deencrypt it.

This worked for me, but think it's not a definite fix. 1) Plugged in bad drive. Msg: driver not load successfully. Drive not recognized. 2) Unplugged bad drive and plugged in a good drive. Msg: driver load successfully. Drive recognized. 3) In another usb slot, plugged in bad drive (leaving good drive in place). Both drives were recognized and could copy data from bad drive to good.

In you case, you have two ways to repair this USB flash drive.
1). Change another USB interface or cable and check whether the USB flash drive is recognizable.
Sometimes, it may be also caused by damaged USB interface. So, open this USB flash drive and change another USB interface or cable. And then, you can try to restore all wanted documents back.
2). Ask some professional drive shop for help.
If your friend really needs to rescue this USB flash drive, you can take it to some professional fixing shops and see whether it is repairable. Just find a reliable shop.
