Note: The jumper pins on the end of the drive determine master/slave status. Directions are on the drive case. In the future, consider keeping all data on a separate partition from the operating system. That way, if you need to re-install, the data is safe. Even if you upgrade.

PS Try not to touch the exposed circuits and ground yourself by frequently touching the case metal. This is the static season.
