Hello, I have tried taking it out of its case and that does nothing. I have also tried it in 2 different computers, a laptop running Win 7 and a desktop running VISTA. When I click on it in my computer it says "Please insert a disk in removable Disk E:" If I right click on it and click properties, it shows the disk as full and 0 for free and used space. I know the ports are working on each computer, as I can insert a different USB stick and it works fine. It contains some highly personal data and I prefer to not take it to a recovery service ! Do you have any other suggestions ? I HOPE !!!!!!!!
