Hi, I have a problem where my external USB drive, my SD card for my digital camera, any data CD in my DVD drive, and even virtual media in a virtual DVD drive are all undetectable. This is just recent too, they all used to work fine. For my external drive and my SD card, It shows the drives in My computer, but when I try to open them it asks me to format, but I can use my SD card through the USB connection on my camera (I normally use it through built in card reader). As for CDs and virtual CDs, it just asks me to insert a disk.
My computer is only a few months old, and I'm running Vista home premium. Any help would be greatly appreciated.
