Conver GPT > MBR (Emergency Transfer)

I need to know how I transfer GPT to MBR… For starters why is it GPT when it’s only 2 x 2TB 4TB Drive… I need an emergency transfer but can’t transfer files why is this forum DEAD ?


The partition on the drive is not GPT nor MBR 

NAS unit comes on ext3

Yes, it is GPT. But why would you need to convert it? All modern OSs support GPT natively… And converting to MBR requires erasing the data, unless you know EXACTLY what you’re doing.
