Based on what I’ve been able to find, it appears this drive needs to be reformatted before it will be recognized by either/both Mac OSX 10.8.x and/or Windows. Using my MacAir, how can I get the system to recognize the drive so it can be reformmatted?
Check if the drive shows up on Disk Utility and follow the steps on the link bellow to format the unit.
