What exactly did you click to see this getting started information? If it was a document found on the drive, then the drive can't be unmounted until the document is closed, & possibly until the application displaying it is quit.
Also, when you follow the instructions & click once on the line with the size (in GB) for the SimpleDrive in Disk Utility's list, you should see at the bottom right of the Disk Utility window a line that tells you the "Partition Map Scheme." What is it?
