Windows 8 Create a Recovery Drive fail, wipes all partitions on target drive, not just partition/drive letter you specify

Just thought I would document an unexpected behavior while creating a Windows 8 Recovery drive. Scenario: - had a 750GB USB External drive attached that had 5+ partitions on it, including a couple empty 150GB NTFS partitions - I had a Windows 8 machine that I wanted to "create a recovery drive" for - attached the USB drive, one of the 150GB empty partitions was drive letter G: - started Windows 8 "Create a Recovery Drive" from Start > Apps > Create a Recovery Drive - it quickly scanned the system for available target storage drives - it listed a few drives, I chose the G: drive as I had verified it was an empty 150GB NTFS partition - it promptly deleted *every* partition on the drive, created a 32GB Fat32 partition at the beginning of the drive, and copied the "Recovery Partition" (I checked that checkbox ON during he Create Recovery Disk steps - luckily I didn't have anything important on the 750GB external drive (I think! .. with age, my memory isn't 100% anymore you know) I was not expecting it to wipe the entire physical drive, only the G: drive I had pointed it to Wow.. thanks Microsoft.
