I've been using a 60gb external hard disk which I bought last September.I've formatted the disk and rename it as "leyza's" and have no difficulties in using it in my laptop or others before this.The disk was not in used for about 4 days..and when I plug in through USB recently, there is no autoplay window and no trace of new disk at 'my computer' as usual.But,there is safely remove hardware icon with different hardware's name,not like the one before.How can I recover all my files saved in the disk.Please help me..
