Dear all, I am at the verge of losing valuable data in my external USB stick. I performed a re-installation of MS XP on my table PC. I did not realise that my external USB stick was still attached on my PC on while I preformed the re-installation of MS XP. After the re-installation, I could not access data from the USB stick any more. I made repeated attempts. I even tired to open the USB on my laptop PC. Yet no success. I continued getting the message "you need to format the disk on drive G before you can use it". Does anyone know how I can solve this problem. I have valuable data on it.
