Well, I went into the Disk Utility and veryfy the drive and the error messages appeared as per the attach captured image below:
I then restart the computer and hold down "Command+R" till the "Apple Logo" appears and releases the keys.
I selected the bottom most option (Disk Repair) and selected the volume and clicked "Repair Disk". Within 5 mins, the (green color) message reads "Your disk repaired successfully" and I gain back all my lost/hidden spaces to what I should be getting...
Kappy, thanks for your prompt reply. Really appreciated it. Cheers!
