My Sony laptop (NV190) would not read my new Sandisk 512 Memory Card (MagicGate) in the builtin card reader, even though it works fine in my Cyber-shot DSC-P200 Digital Camera. Sony had me download and install some updates to the drivers on the laptop but it didn't work and in the process I had to use my original Memory Card 32 (MagicGate) that came with the camera and the laptop would read fine. During the process it wiped the format of the original card and I get errors on the PC saying "target drive not found" when i try to use the the software Sony tech indicated. The camera says the card needs to be formatted but I am not sure how. help?
