Thanks very much![:-)]( "Smile")
Yeah. That's as simple as they come. The one component near the M.2 connector appears to be WAKE/RESET related, so I don't think there's anything clever there with SUSCLK. Assuming the drives you have are the SN350/550/750(X) then that seems to say there's something either with the power supply, power sequencing or the SUSCLK pin that can make them wake up reliably without 32KHz.

For sure! It may be we just do a revision and add the xtal circuit for a modest price bump and a quieter life if there's no simple way around![:-)]( "Smile")
