Allow DVR Examiner and WITNESS to select which hdd partition to scan

When someone who doesn't know what they are doing tries to recover files from the hdd of a DVR they often mistakenly end up putting an NTFS partition on the drive so Windows can see the drive, this then renders the drive unreadable by DVR Ex/WITNESS as it finds the NTFS partition and stops the scan. It would be great in those circumstances if there was an option to bypass that partition to get to the DVR partition.
