you need to format for exfat so windows and mac can read, if its formatted as fat 32 a mac cannot read, which type of computer are you running and have you tried it in two different computers?

Virus or Trojans can run some process that keeps running in background. This not only harms the computer, but also prevents the pen drive from formatting as it shows that the drive is in use. Remove and re-insert the pen drive, don't double click on drive and cancel autorun operations if it starts automatically. Run a virus scan on pen drive, this will help fix the issue. Now format the pen drive.

People often feel panic when I see this. If I format the drive, will I lose all my data? If not, how could I get access to my files?

My take is that you may have to format the drive and then use recovery software to recover your files.

Here's some information about file recovery, think you need to take a look, very useful

Scanning by what? What OS?

Hi, what's wrong with your flash drive? The most common thing is data loss. If it is so, you can try 4Card Recvoery to recover your files on your flash drive.

Two of the most common causes of I/O (Input/Output) device errors are driver based. Typically, either the device's driver is not enabled or it is out of date. The driver component has an important function, as it acts as a motorlike force that propels USB/plug-and-play hardware into a driving action within the computer. It is the connecting communicating link signaling the CPU to a desired movement. And while not all I/O device error solutions are simplistic, as a good starting point, you can try troubleshooting using a few basic steps, and you might not need to attempt anything else. Access "Control Panel" from the Start menu and then choose "Performance and Maintenance." Click "System" and then go to the Hardware tab and click on "Device Manager." Find the device that is registering an error by expanding the nodes of the appropriate category. If the device has a red "X" on the icon next to its description, the hardware is disabled; proceed to Step 4 to enable it. Otherwise, go to Step 5. Go to the General tab and click "Enable Device" found under the Device Status section; then press "OK." (Note: You may have to follow prompts, as indicated through an enabling device wizard. If you do, continue to click "Next" and follow the prompts until the process has completed.) Test the hardware. If an error is shown, proceed to Step 5. Go to the General tab and click "Troubleshoot" found under the Device Status section then press "OK." Follow the prompts to solve the issue. If an error is still shown, proceed to Step 6. Go to the Driver tab and click "Update Driver." Follow the prompts until the process has completed and then test the hardware.
w7 First, please disconnect all USB devices and then perform the following steps:

Click "Start" button, type "devmgmt.msc" (without quotation marks) in the "Search" bar and press "Enter". Click "Continue" if necessary.

In Device Manager, double click to expand "Universal Serial Bus controllers", right click on the Host Controller, click "Uninstall" and click "OK".

Repeat the step 2 to uninstall all items under "Universal Serial Bus controllers".

Then, restart your computer and Windows 7 will reinstall all USB controllers automatically. for xp or earlier click start right click on computer select properties device manager scroll down universal serial bus controllers you could see a yellow question / exclamation mark? ! or a red X you will need to update/reinstall drivers right click to reinstall drivers if you can see your usb drive but its not working ports (com&lpt) right click update driver if this fails to fix the problem Check the USB leads that attach to the motherboard usually red white green black make sure they are securely seated and have no dust build up on them dust will cause static and a lot of unforeseen problems to a computer and its parts Hope this helps.

Can you tell more information about your USB driver? What your problem is? Data problem or unrecognized problem?
Anyway try 4Card Recovery, which can solve all the situations above. How to Recover Photos Videos off SD Card after Formatting Unformat SD...

Kingston... | Answered on Mar 22, 2014

The drivers must be up to date and written for your device. If there are no drivers, it will not communicate and thus it may look like it is working and in place, but the linkage is not there.

The best way would be to format the card. There is an industry standard program for that here:
Its free.

Sometimes it comes with a software, you must have erased it.

Kingston... | Answered on Mar 12, 2014

I'm guessing that you got an error saying that something else is using this device, therefore you cannot format it?

If that's the case, you could do a lot of stuff to find the process that's using it and shut it down, but what's a lot easier is to just reboot into safe mode and try it again.

If you have windows 7, type "msconfig" into the search bar when you click your start orb. Hit enter once it finds the program. Click on the "boot" tab, then check the "safe boot" check box. Click apply then ok and let it reboot. Now you're in safe mode and nothing should be in your way of formatting your flash stick. :)

To get out of safe mode, follow the above directions again and just uncheck "safe boot."

If the stick isn't being recognized by windows at all, like you can't even see it in explorer, then chances are it's not initialized. Let me know and I'll walk you through that process next if none of the above helped and this is the new problem.
