I looked at the details provided in my system report/storage and I noticed that it appears I have a hard drive of 499.05GB and an additional SSD drive of 499.42GB. Does this mean I have 1TB of data? I only have 139GB available so do I have 500GB 'hiding' somewhere? (If so where??) I am unsure how to interpret this information- why does it list both storage types? Is it duplicating the information?
