Files on a flash drive canbe corrupted if it is not removed from the USB port properly. Before removing the flash drive click on the Safely Remove Hardware icon andthen click on the flash drive you want to remove and then remove the flashdrive when the computer message says it is Safe to remove. To restore the flash drive to working order you need to format the flash drive,BUT you will lose the data stored on the flash drive. If you need the data on the flash drive these WEB sites may help: - Data and Digital Photo Recovery www.artplus.hr/adapps/eng/dpr.htmwww.CardRecovery.com
Simply UNPLUG YOUR COMPUTER FROM THE POWER SUPPLY.
Yes that's it! Note that this does not mean just turning off your
computer because modern computers don't really turn off when you press
the power button as the motherboard still gets power.
First to explain, the motherboard is where all of
hardware of the computer is connected to, including the USB ports.
Sometimes the motherboard needs to be "rebooted" also because something
can go wrong, i.e. all your USB ports suddenly stop working. The small
microprocessor on the motherboard will reload the drivers and your USB
ports should be back to recognizing all devices!
So first turn off your computer using Shut Down or
pressing the power button and then UNPLUG it from the wall outlet. Let
it sit for about a minute and then plug it back in.
Hope this helps someone fix that pesky "USB device not recognized" Windows error!

I devised these simple steps that tend to remedy quite a few issues with most USB portable / external hard drives and OTHER devices (though not always)
A few things to check but assumes USB and Windows for other interfaces / operating systems (mac/ Linux) similar steps may be adapted to suit.
1. Ensure it is connected directly to the computer to a USB 2.0 port not a USB 1.0 port as this can have effects on performance and reliability
2. Use only the cables that came with it NOT one that fits that may have been lying around or is longer. Not all USB cables are equal even though they should be)
3. Do not connect through an external USB HUB unless that hub is USB 2.0 AND has its own power supply.
4. Use ONLY the power supply that came with it if it has an external power supply Don’t use any other unless you know it has both the same voltage and current rating e.g. 12V 500mA anything rated below that would not work properly.
5. Always use the same port for connecting your devices. Some devices do not like being switched about. If switched they may want to install software / drivers again. This can be especially true if you move a HUB to another port
If you checked and fixed anything there and still have issues then check your hardware from CONTROL PANEL / SYSTEM / HARDWARE. Any exclamation marks by hardware need fixing before you investigate any further
USB flash drives can fail for no apparent reason. Sandisk Cruzers are especially bad for this.
USB hard drives should be treated with extreme care. This is a real hard drive ! and knocks and bumps can quite literally kill them.
It is possible to remove drives from the enclosures in most cases and connect directly inside a PC to fully check it.
Note that if you hear a drive clicking or pinging this could be the worst thing you would hear. Known as "The Click Of Death"
If none of the above steps help look at updating the drivers from the manufacturers web site in the support section.
It sounds as though the problem is with your notebook, rather than the flash drive. Specifically, with the USB port you are plugging it into. If you have another USB on the notebook, try switching between the two, and see if it behaves any differently. Another thing that can cause a problem is if the USB port on your notebook is not USB 2.0. The older ports (as in, an older computer) didn't have nearly the transfer speeds of the newer standard.
Also, are you trying to run multiple USB devices on your notebook at once? That could cause problems as well.
Could you tell me whether the USB ports are providing power or not....
i.e do you get any indication in your flash drive that it is getting power (a light or something)
If you are getting that then there is a problem with your windows installation.
You might have to perform a clean format
if there si no indiction of Power then there is a hardware problem and you might have to replae the Usb port or see the connections
Please do reply to the post and we will see if something can be done.
