Okay, I have a brand new Targus card reader and an older Impact 128MB SD card from a Kodak Easyshare camera. When I put the card into the Targus, it lights up. The card reader shows up on My Computer as F but when I click on it, it asks me to please insert a disk. This is my second time using the card reader - it worked just fine about a week ago the first time I used it. Any ideas? Tried to get it to read on my Compaq laptop and E-Machines desktop with no luck!
