Hi, The reason you're seeing this is because of the "missing" internal storage card. You need to fix that issue first. When you connect with the usb you will get a drive letter on your PC (this should be where you're getting the error as you're trying to open the drive). Instead right click on that drive letter and format... use the default settings and the quick format, it might take a while. This method restores the internal storage.... OR use the hot fix.

It sounds like you're phone is on default to connect via disk drive mode. You want to be at the place where you can choose your connection. Go to start/settings/connections then click on USB to PC check the dot for Active Sync uncheck the box for Enable faster data sync. Check the box to ask first (this enables a popup window to show whenever you connect the phone to pc. the popup window gives you options to active sync or connect diskdrive mode so you can choose your poison). As I stated before diskdrive mode shows storage card files only and active sync shows both main drive and internal storage card.
