Corrupt Wav files if unit switched off before recording stopped

At gigs we have had a couple of times when the recording was not stopped before the unit was powered down by a bandmate.

The data is on the SD card but unreadable and showing 0 bytes. Tried repair in Audacity, etc. to no avail.

Is there a known file repair or plans to ensure interrupted recording are still accessible?

There is a process described here - https://support.allen-heath.com/hc/en-gb/articles/4402934227857-SQ-Recovery-of-corrupted-SQ-Drive-recordings
Although the article has been written with SQ in mind, it would certainly be worth trying with your SD card.

Thanks,
Keith.

The SQ process worked perfectly for me after thinking I lost some recordings from a great show.
Seems to keep happening at shows but never once in practice, so I have to assume the power cable is getting yanked when I’m not looking.

Not as much to worry about knowing this, thanks for the suggestion!
