My cloud mirror

I connected my wd 4TB external HD (with about 3.5TB of data) to my My Cloud mirror as my computer usb socket was playing up and I just wanted to test on another device

The mirror has 2 x 4 TB drives un mirrored with 5.5TB of data - so about 3.5TB free

since then I cannot access and both are flashing madly obviously data is being copied but dont know which direction and can’t stop

If I unplug something no does I will cause a corruption but am worried about all the data I have
