I have looked at other posts but they haven't helped me. I previously had a Blackberry Tour. When tethered to the computer the sd card was available to use as any other folder or directory. With the Droid it is shown as Drive F but can't seem to use it to drag and drop or anything else fro that matter. If I right click it and look at properties it says it has zero bytes and is all filled up? If I left click it, it asks me to but a disk in the drive. I bought my Droid privately and it had some info on the sd card. I thought that might be the problem so I formated it. Didn't change anything. Help!
