Question

Hi There, I have an external Hard drive and yesterday it was working fine. This morning I have plugged the USB in and it brought a message saying ( you need to format the disk before you can use it ). Its an external Usb hard drive and the files inside are very very important to me. I have tried to operate it in more than one computer but the same message appeared. Please find me a solution please. :( Thanks, Abdullah [e-mail]
