The error counter on SQ-Drive counts the number of times the audio stream has an issue, so this is not to do with the SQ itself, but with how the drive is coping with the audio stream.
Do you know the read and write speed of your drive? As SQ-Drive requires a speed of at least 40 MB/s to cope with 16 channels of 96kHz 24bit audio.
Alex, is there a list anywhere of compatible drives? I see one for the QU but cannot locate one for SQ. My dealer told me the drive he supplied is to spec, but we are still having this issue.
