SOURCE: Remove the write protection on 2GB USB Kingston Data Traveler 100

Found this on Kingston site, doesn't help much but may point you in the right direction.

Unfortunately this unit does not have any security or write protection feature. If you receive a write protection message with this drive, check for the following:

1. Verify that you are allowed to write to removable storage devices. There may be a security setting in the OS that disables write access to removable storage devices.
2. Make sure you have not enabled write protection on the drive by using a third party software.
3. If none of the above apply, the drive may be defective.

I sense that your usb memory is equipped with a physical write protect switch that you may have overlooked. Locate it, switch to the "non-writeprotected" (unlocked) mode and everything should work normally. Good luck!
