Same problem here. Did multitrack recording, checked that everything was running ok – ssd led was blinking . Stoped recording after 1 1/2 hour, it stoped and everything was ok in display. Checked that Ssd led was´nt blinking anymore – ok. Unmounted ssd and checked in computer. Lib was ok but wav files was 0 kb…. Tried “Right click on the device > Select ‘Properties > Tools > Error-checking’ > Click ‘Check'” as instructed in this forum but files are still 0 kb. Please help!
