Try the flash drive on another computer to see if the problem is the drive itself. The drivers for a USB flash drive are built-in on Windows 7, so the problem is NOT that the drivers aren't loaded. The problem is almost certainly that Windows is not correctly identifying the device, which is almost always a problem with the device itself.

If the drive does work in another computer, be sure that it is formatted and put a couple of files on it and make sure that the computer can read those files - then try the flash drive on your laptop again.

If this flash drive works on another computer and still doesn't work on your laptop, try another flash drive on your laptop. If the other flash drive gives the same error, then you will probably need to repair your Windows installation - which is a job best handled by someone with more experience unless you are willing to risk whatever else you have on the laptop by just doing a full reinstall of Windows.

This happens when a malware or a virus attack on files and its not able to recognize the drive. One option is to put the flash drive in a computer which is having a updated Antivirus software and most of the times, it recognized and remove the virus.

This mostly happens when you remove a drive without Safely Remove drive function.
Try the USB lead - restart your computer - Change the Drive letter using the disk management Plug the USB back in hopefully it should reinstall the driver and you should be able to see it.

It's looking for the memory card or usb drive.
If it already is in then wiggle it a bit to see if all the contacts are good

(Windows 7) - Control Panel - ( make Large Icons) - Folder Options - View (check "Show hiden files,folders and drives"). Then go to C:\\ and look for "Ur-Smart Data" Folder (Delete it). (That's solution!) for more contact me : resul-rustemi@hotmail.com

My apologies if this message finds you long after posting this problem , but I am currently working through a backlog of problems that never got answered and hopefully this info can still be of use if not now possibly in future.

Please download Disc Digger HERE. This is a free tool you can use that works very well and there is no installation required, just run the program once you downloaded it.

Once you have connected the memory disk / hdd to the computer , run the program.

On the program , select the dig deep option for accidentally deleted files or dig deeper for a formatted drive. Then select the disk you want to do the recovery on and run the program.

The data will be displayed and you can recover it from there. This will only work if the card has not been used since the data was lost. Save the files to a location on the computer hard drive and not back to the disk it is recovering from as this will overwrite the other pictures that still needs to be recovered.

Some of the properties of the files may become lost in the recovery but the pictures should be fine.

You will also only be able to recover certain file types using this method.

Feel free to ask if you need more assistance.

Kind Regards
