Thanks Bob. Solution would seem to be a solid state of some sort. Does anyone have any recommendations for a USB stick or SSD drive that works well?

Hi Bob, I hit stop and then wait while the QU-PAC clears its throat. As per the A&H advice (I think) we tend to just leave the recording running for the whole show, breaks and all. So, the post-stop processing does quite often take a long (so much so that I have wondered in the past if the unit has frozen up).

There have also been occasions when the plug has been pulled before I’ve had a chance to go through the proper shut down routine (or where I’ve forgotten to go through the shut down routine before pulling the plug myself if I’m being completely honest).

I’ve not noticed a link between any file problems and not following the shut down routine – but until you mentioned it, I’d not been looking for it. Could that account for it d’you think?

Thanks garyh.

Did a bit of experimenting in the studio today, reformatting the drive and also getting away from the ridiculous SPLs of a live situation. As is always the way, I couldn’t reproduce the error with our usual disc (a 2TB Lacie rugged USB3). Perhaps vibration from the low frequencies could be the problem? Has anyone had this same thought? And if so, has anyone had any success trying to isolate the disc from vibrations? The hifi community seem to use a ‘sandbox’ to isolate turntables from acoustic vibrations so maybe that would work…

I also tried a spare USB ‘stick’ (a SanDisk) but I got a lot of errors while recording and a lot of stutters on playback. Similar situation with a Kingston one. Does anyone have a recommendation for a suitable USB stick or SSD? If I’m going to have to reformat for each event then 64 GB would seem to be ample – that would give nearly seven hours of multi-track recording.

Documentation seems to suggest that you should reformat your drive before each session. Again, be good to know if anyone has solved this problem (or any other) by reformatting each time.

Finally, I should also add that my initial description of the problem was not quite accurate. It’s not that the audio files created are silent, rather that they seem to be corrupted. So, all 18 files in the multitrack folder are the same size (say, 1.6 GB for example), but some of them won’t open (either in Mac OSX or iTunes).

I get this problem too (QU-PAC). Always different channels which don’t record even though the scene is the same on the unit. Saturday night Tracks 1, 4 and 10 are silent whereas the previous week everything recorded fine.
