MBR to GPT Conversion

I bought a 4 TB Seagate drive and allowed Windows 7 to format it, creating a 2 TB drive and 2 TB of unallocated space that can't be recovered because MBR doesn't recogniz anything above 2 TB. Will Partition Assistant Professional convert a disk that is active with system files on it from MBR to GPT? Also without any data loss? Please let me know. Thank you.

    Yes.  This conversion will work.  The more data present on the drive the longer it will take.  Also, it is recommended that you backup your data before making such a conversion.  While the software supports doing this on the fly, a good backup is ALWAYS recommended.
