My Inspiron does not recognize usb hd drives when I plug them into a port. This is Dell is using a Windows7 update that was installed over the original Vista software. My backup is stored on a Maxtor USB drive and I need to access it to retrieve some files. Can you help me here?

Have you tried different usb ports? Also check the file explorer to see if the disk is mounted. Sometimes I have usb keys that mount, but don't automatically open making you think nothing happened.
