Are you signed in as the administrator

USB ports and devices make connecting to another computing device convenient.
USB technology has been around since 1996, and is a feature found on most modern computing devices.
If your device is denied access to one of its USB features, do some troubleshooting to isolate and resolve the problem.
Viruses
Some computers come with a security feature that automatically denies access to a USB device, such as a flash drive, if harmful content is detected.
Installing an anti-virus software application and regularly scanning the computer and any connected USB devices can help you avoid experiencing denied access to a USB device.
Avoid opening USB flash drive files that you cannot identify or do not recognize, as these types of files are how viruses find their way onto unprotected computers.

Incompatibility

Inserting an incompatible device into your computer's USB port can also cause you to be denied access to your device's USB features.
For instance, if your computer supports USB 1.0 technology and you insert a USB 2.0 or USB 3.0 connector, the computer can experience interfacing problems that may cause a "USB access denied" prompt or situation.
If other USB devices begin to malfunction after inserting an incompatible USB cable into your computer, turning the computer off and back on again may resolve the situation.



Formatting
USB flash drives, also known as pen or thumb drives, are among the most common types of USB devices used in conjunction with computers.
Most USB flash drives are formatted using one of three types of formatting methods: FAT16, FAT32 or NTFS.
If you've formatted a USB flash drive using one method, used it on the computer and then reformatted the drive using another method, you can be denied access to the flash drive through the computer's USB port.
Wiping the flash drive clean and reformatting it again can resolve this type of problem.

Considerations

Many computer accessories, including printers and pointing devices, connect through the machine's USB ports and can interface interchangeably with multiple computing devices.
This feature increases the risks of picking up viruses and experiencing unauthorized reformatting. Limiting the amount of computers your USB devices accesses can help you avoid these situations.
Damaged USB cables can also make it impossible to access USB devices when they are connected to your computer.
USB cable damage usually occurs at the points where the cable and its connectors meet. Replace any damaged USB cables.
You have to be the computers administrator to change any values on any hard drive on your computer.
Click start control panel user accounts on the users tab click the name of the computer Administrator you must have full control.
Click start click to open on my computer you should see your usb drive could be E: or something right click select properties there will be an array of options
select the sharing tab option then advanced sharing make sure you have a tick in the share this folder box then click permissions make sure you have all 3 boxes ticked full control changes and read in windows 7
If you are running a Windows XP OS then you might be able to:
Click start right click on my computer select open
Right click the icon of your Flash Drive (It should be F:/ or something)
Click Properties in the menu that comes up
Click the Sharing tab
Click permissions
And finally, click Allow next to Full Control.

Put the card back in the computer and format it using FAT (not NTFS) format. In the format menu, you'll see the file system pull down option, choose FAT and try and format it again.

Thanks Mark

Put the card back in the computer and format it using FAT (not NTFS) format. In the format menu, you'll see the file system pull down option, choose FAT and format again.

Viewing the back of your computer, you will see a large thumb screw, on the right side of the computer case.

It's to the right of that round ventilation opening. (Round shape with multiple holes in it)
Unscrew the thumb screw to the Left, to loosen it.

The side panel that the thumb screw is in, pulls back towards the rear of the computer.
If you look, there is a place to put your fingers at the end of the side panel.
(Raised 'Hump' in the sheet metal of the panel)

Hold the top of the computer case with one hand, pull the side panel back with the other hand.

NOTE*
The computer MUST be unplugged from power before proceeding!

Not only is there a possible issue for Your safety, but also the computer's!
You will fry out the Ram Memory stick/s if you remove, or install with the computer plugged into power.

Also,......there is an Anti-Static issue that needs to be addressed, BEFORE you reach inside your computer

Your body carries Static electricity.
Static will fry out the hardware components inside a computer.
(In a Flash!)

Work on a table. Computer unplugged from power, computer case open. TOUCH the metal frame of the computer case BEFORE you reach inside.

TOUCH the metal frame Before, you take those ram sticks out of their protective antistatic bags.

Should you get up for any reason, walk away, then return, Touch the metal frame again.

Refrain from touching the gold plated contact pins, on the bottom of the ram stick.
You can handle the ram stick anywhere, but on those contact pins.
The ram stick is coated with a see-through plastic.
The contact pins are not.

Should you need advice on how to remove, and install ram memory, please state so in a comment. (Top right of page)

As this has happened to me recently... I'm not sure if you have used the memory stick in the past but if it has never read the stick then it just may be a bad one. If you have used it you have to remember that memory sticks are very tempermental. They will work one moment then not work the next. Always keep your thumb drive backed up on a hard drive. That is your best bet

try using this software to format it..http://www.transcend.nl/support/dlcenter/ORT_Software.asp?Link=OnLineRecovery.exe

it may be lost, safely remove your hardware befor you get off from the computer

Turn power off and unplug power from computer.
Unplug printers,backup drives and speakers.
Open case and unplug power supply from the board.
plug power cord back in press the power button.
Of course nothing will happen.
unplug power cord again.
plug power supply back into the board.
plug power cord backup and press power switch.
If nothing happens unplug power cord again.
pull out your memory sticks and plug cord back in and press power button.
Of course not much will happen.
But really something is happening to your computer so continue.
Pull power cord and replace memory sticks.
replace power cord and press power switch.
Continue this pulling out pci cards one at a time until you find out what the problem might be.
Try different keyboards and mice too.
Good Luck
