I've been extremely frustrated for several hours trying to mount my Droid on my PC running Vista 64-bit. It mounted properly the first time, I pulled down the notification tab, then clicked mount, etc. It worked for a few minutes, then I started getting the "Please insert disk" error. And I've been getting that since. I've manually uninstalled the drivers multiple times, and at a few times, it will mount, and I will see the files, but seconds later, I get the "Please insert disk" error.
If anyone knows a fix for this, please let me know. Oh, and it isn't the Card, I was able to put it into a card reader and it worked fine.
