First, you will need to download and install Desktop Manager to get drivers. You can download and install just the drivers, but you'll have to look to find that--easier to just go to blackberry.com and download and install Desktop Manager on your computer. If you haven't done this, go ahead and do it now.
On the BlackBerry handset, there are multiple parts to enabling mass storage mode. In options, enable media card support, enable mass storage mode support, and then choose the setting for auto-enable. Set it to prompt, or to yes. If you set it to prompt, be sure and select yes to enable when you connect the BlackBerry and you are prompted.
When you connect to the computer (and make sure you are connected), Windows will automatically assign it a drive letter. If you have Explorer running, you will see the BlackBerry media card appear.
Pay attention to the USB port that you use. Hubs, keyboard and monitor ports, and so forth are commonly a problem. Use a port on the computer. If you still have trouble, try other ports.
