Try right clicking on it in control panel. Go down the list and see if there is anything about write-protection. If not select properties at the bottom of the list and look through the tabs for w-p. Finally look on the device itself. Sometimes there is a smal switch. You may need comething long and thin to get at it. It is often well hidden. Hope this helped!
Arun Jaganthan-Whether your USB is write protected,If there is no switch or in registry u can't find Storage devices.
A common security concern at organizations is allowing users to plug in a usb flash drive, because they could so easily copy corporate data.
Since Windows XP SP2, you can disable writing to USB devices altogether using a simple registry hack. Here it is:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies]
"WriteProtect"=dWord:00000001
You should also check your dive letter assignments (hit run and type diskmgmt.msc) Make sure that your drive letter is set correctly!
You can also just download registry tweaks to enable or disable writing to USB drives.
