USB stick/flash drive noise

Hi,
I am having a problem of noise (sounds like clicking) when recording onto a flash drive, I’ve tried re-formatting them and I got even more noise during the format. The drive has been used sucessfully in the past but this is new. I’ve seen the forum on computer connected issues, we are connected to a pc running windows 10 but that seems fine.
Any ideas?
Thanks.
Martin.

Is the St3 analogue input turned up? That can pick up USB noise.

Connect something to St3 normally prevents the pickup.

It should be obvious on meters if that is the issue
