I am using ATEM Mini Pro Extreme. I have 2 identical Crucial X8 1TB SSD's. SSD "A" works perfectly. Using SSD "B" results in an amber light on the ATEM disk button but recording does nothing. However SSB "B" works on computers in all respects. Any help is appreciated.
Oops! Someone who will remain unnamed formatted the drive in NTSC not FAT.

. Works OK now.
