I have two 8 TB Corsair Force MP600 Pro SSD in the case, it does not copy.
First step: Insert SSD into slot A, make file system (I have tried various, APFS, HFS+, exFAT), write data. Transfers are limited to around 800 MB/s, which is to be expected.
Second step: Insert second, empty SSD )same model) into slot B, disconnect host, press copy.
Problem: The 4 LEDs light up for a second, then nothing happens.
I've tried various different press-button-durations, waited for 2hrs everytime (ample time for 2 TB at 800 MB/s expected internal bandwith for copzing >>25%) - but the A/B LEDs do not flicker and the 25/50/75/100% LEDs do not come on.
How do I proceed ?
