0 byte WAV file problem - many things tried - none worked
« on: September 25, 2013, 09:43:26 AM »
Hi there!

I recorded a huge act at the awesome Aviva Stadium in Dublin last week, and there was a scheduled intermission during the show so I stopped the recording, aiming to resume it later. When I stopped it, the recorder (Tascam DR-08) didn't work as usual, but instead shown me an error message that I can't remember word by word, but something like "Can't write file". It was a freshly formatted micro SD card (formatted by the recorder itself) and I was bummed that the first part of the recording had been "lost".

But oh, oh, when I got home and checked the SD card, it seems that the disk space is THERE, t'was consumed after all - I attach a screenshot. The first file (pre-concert levels checking, settings, etc) is fine. The second file (first part of the show) is empty. Third file is the 2nd part of the concert recorded and it's fine (besides a battery fail that cut the last 10 minutes of it, but anyway, that's another matter and completely my fault).

It's pretty important to recover this recording, not only because it was a primal concert and almost the end of a 3 years world tour, but also it was very intense personally speaking. I'm quite desperate as to what to do right now


What I've tried so far:

-open the file as a standard audio file with Audacity - NO SUCCESS
-import the file as raw file with Audacity, trying different settings - NO SUCCESS
-recover the file with Back2Life - NO SUCCESS
-play it on VLC - NO SUCCESS
-convert it with Format Factory, Little Traders Help, etc - NO SUCCESS





Any ideas, anyone? Thanks in advance ;D

I cannot speak for the DR-08, BUT the DR-680 when you run across a zero file size has been a bastard to recover including using some higher end software.  You might try some DOS commands on the file, wish I had an answer, good luck

I had the same issue a few years ago with a rockboxed iriver when my battery died part way through a gig. I eventually sorted it out by using audiohack (see link in the hyperlinked thread above)

Good luck.

Thank you Brian, I knew the issue had been discussed some times in the forum but I couldn't honestly find any suitable thread - I guess I should have read the reference readme's too. Sorry and thanks again, gonna try some of them.

I have done the chkdsk thing and it's recovered a 573 MB file that's 57 minutes long, although I clearly remember the 2nd file clocking at 1 hour and 13 minutes when I stopped the recording (and subsequently the recorded gave the error message). 57 minutes is obviously better than 0, but also quite worse than 1h13m... Same error as reported here:
http://taperssection.com/index.php?topic=53521.msg732954#msg732954

Now that I have opened the repaired file I am missing about half of it. I am certain the unit was recording through the encore, but the track just ends midway through the main set.

I guess that's better than losing all of it. I've learned my lesson...don't unplug the power cable. Kind of a bummer, but I guess it's to be expected with a new piece of equipment.

Any thoughts on it? I'm happy with what I've saved so far and THANKS again for those who knew the workaround and Brian for pointing me in the right direction, but if I can save it all then I'll be happier than happy ;D

I solved in this way:

1. run chkdsk :[drive letter] /f on the card
2. search for the .chk file that was created on your hard drive (maybe it is hidden by the windows machine, i used a knoppix boot disk to make it viewable) and rename that .chk to .wav
3. use "audiohack"; audiohack /N [file.wav]
4. import the created .raw file to an audio editor (use raw import, not open), like import raw in audacity, usually the machine records "little endian", and choose sample frequency and bit depth you did in the recording
5. now you`ve got the file back (or most of the file until the moment the machine crashed), and go on like normal (mastering if neccessary, then export to Wave, Flac etc ...)

No way, that's all I did a few weeks back but the recovered CHK file weighs just as much as the WAV that results after converting it. It's like the recovered file missed half of what was recorded.

I've given up and just have a 60 or 70% of the total show, which is much more than I had when I came back home with the broken files anyway. Thank you everyone once again :)

Read through this thread regarding the Homegrown Wave Header Repair by pigiron. It has worked for me and others in the past. At the end of the thread there are some more alternatives to pigirons' repair program that may also work.
