I too have had issues recording to the SQ Drive. I have an SQ5 with the latest firmware 1.2.0 r2258. I have been doing stereo recordings to my Kingston DTSE9 G2 16GB USB drive. Every minute or two I have a drop out then the recording picks up right where the drop up happened so looking at the wave form you can not see the dropouts. It seems like there are whole seconds that it drops out for.
I also do not see any errors pop up on the SQ Drive Stereo window which is why I did not realize the issue until listening back the recordings after the gig.
If anyone has any advice that would be much appreciated.
Thanks!
