One of my backup drives is an external 1TB SATA drive. I leave it powered down except when I am backing up. In order for the computer to see the drive, I have to power up the drive and then reboot the computer. Is there a way to mount the drive (Windows Vista) without rebooting?

My backup software (Karen's Replicator), as is the case with most backup software, doesn't back up files that are in use. (I tell it to skip the C:\Windows directory entirely as a global exclusion.) Below is a list of the files that it doesn't back up. Some of these files I know about (in particular, the AVG files) but others are a mystery to me. Does anyone know what these files are? (This segment of the backup log is NOT to the 1 TB SATA drive, but to a smaller USB external drive.)
