Recover Audio-DataBlocks _ Audacity 2.3.2 MacOs Mojave 10.14.6


I’m using the italian version of Audacity 2.3.2 on a MacOS Mojave 10.14.6

Yesterday I started my first recording with audacity. I recordered an important interview for 1h30min and in the evening I’ve made a copy of the project (to be sure that it would never lose any data) and I started to edit it. Today I tryed to open the copy but I discovered that I’ve generated an error: I had copyed the _data folder so his name was “[Name]_data copy”. OK EVERYTHING FINE BUT:

Now if I try to open the original project, the untouched one, and pops up an Error Window that has as title something like (I’m translating from the italian version): “Attention: Audo-DataBlocks files are missing”. It says that it can’t finde 487 Audio-datablocks files.

I have not opened that file from yesterday! How can I find that datablocks?

I attached the screenshot of the Error Window and the Audacity Register (I can’t save or expand the Register so this is how much i can see).

Thank you very much for the help.

Please attach the project “.aup” file for us to look at.

Here it is!
I also found the way to save the Register so here it is. It’s seems it can’t find the files and if I use the search tool on my computer I can’t find them too! (For example Where they are gone?
What’s happened?
registro.txt (196 KB)
Albhey Longo 20 gen.aup (121 KB)

Do you have the folder:
/Users/giorgioaboumrad/Cartelle/Creazioni/Shahrazad/Albhey Longo 20 gen_data


How exactly did you do that?

Yesterday I recorded the interview and Audacity created Albhey Longo 20 gen.aup and the folder Albhey Longo 20 gen_data.
To copy the project I’ve selected the “.aup” and the folder “_data” and I’ve copied them and pasted in the folder Shahrazad so I created Albhey Longo 20 gen copia.aup and the folder Albhey Longo 20 gen_data copia and I’ve started to edit them yesterday evening.

Today I’ve tried to open Albhey Longo 20 gen copia and a first error message comes up but I’ve understand it: Audacity was searching for a folder Albhey Longo 20 gen copia_data and it can’t find it. Ok.
If I’ve lost the edited version for this stupid thing I can understand, it’s a pity but not a big deal and it’s my fault.

The problem is that the project Albhey Longo 20 gen.aup and the folder Albhey Longo 20 gen_data were untouched, unedited and unopened after the recording! So I can’t understand where are the files it is searching!

In a first time I thought that the first error (the absence of Albhey Longo 20 gen copia_data) was the cause for the second error, the audio datablocks missing, but I’m not so sure!

You can’t rename Audacity projects like that. In fact you shouldn’t manually rename projects at all.

Try changing the names:
…/Shahrazad/Albhey Longo 20 gen copia.aup
…/Shahrazad/Albhey Longo 20 gen.aup

…/Shahrazad/Albhey Longo 20 gen copia_data
…/Shahrazad/Albhey Longo 20 gen_data

For future reference, the safe way to change the name of a project is to open the project in Audacity, then
“File menu > Save Project As…”
and enter a new name for the project.

Ok, but let’s forget the copied project: when I open the original one he says that he can’t find 487 audio data blocks. Where are they? Why they disappeared? What I have to do to be sure that’s will no happen again?

Audio data blocks do not normally go missing, though a crash, or removing the storage medium, or shutting down the computer, or even the computer going into hibernation while Audacity is open, can cause data blocks to be missing from a project. In your particular case, we don’t have enough information to know what caused the problem with the original project.

I would however recommend upgrading to the current version of Audacity (2.3.3) which is available via the Audacity website:

Thank you for your time!

When you finish an important recording, export the work as a perfect quality WAV sound file in addition to anything else.

File > Export > Export as WAV >

If you have to edit or change the work, do it to a copy of the WAV file.


Use good filename hygiene. Upper case, lower case, numbers, -dash- and underscore only.

Use ISO dates such as 2020-01-21. No slash marks.


I’m professionally obsessive, so I don’t use spaces in a filename either.

That will produce this file…


But Windows and sometimes Macs will try to hide the .wav extension. You can discover the real filename with Media Info.

Or tell your Mac not to hide the extension in the first place.

Desktop > Finder > Preferences > Advanced
