I am actually having the same problems I will put in a DVD to copy and it will Copy just fine and then when it asks for a clear disk its like it erases my DVD drive which is my E drive...I have a Dell Inspiron 1505 notebook...umm actually as we speak it is actually working so I dont know what is going on to tell you the truth I have checked the forums and done everything that everyone is saying....which is basically not much help lol anyway i bet you it will burn this DVD and then when I put in another one it will erase it so I will have to restart my computer and then my E drive will be back but it wont copy does anyone have a fix for this or what??? stupid vista
