Missing Audio Data Blocks

I cannot believe this keeps happening to me. This is the third time in two months 3 out of the 6 times I have tried to edit a podcast. I've removed and re-downloaded Audacity each time, and it continues to happen. This is so incredibly frustrating because hours of editing have now been wasted because the only option is to treat the missing audio as silence. Why does this happen, and why isn't this being fixed? I realize the program is free, but come on, it should at least be usable.

Here is a little bit of the log. What can I do to keep this from happening, and wasting my time?

why isn't this being fixed?

Because the defect has to happen to a Windows developer reliably enough to identify the problem. Without that, it's pure guesswork.
I've removed and re-downloaded Audacity each time

Did you reset Audacity? Audacity keeps preferences and settings in a separate location from the main program to make upgrades easier. I think Windows has a setting to reset everything when you install or reinstall it.

Odd missing data can be caused by an overactive virus protection program or a mis-behaving external plugin, effect or filter. It can also be caused by a drive filling up although that's a lot less likely. Is the machine doing anything else while you're editing?

Are you editing on an external USB drive, network connected drive, or cloud drive? None of those is recommended.
to edit a podcast.

Can we assume you are editing a copy of the podcast? It is recommended to export a WAV (Microsoft) of the raw recording before you do anything else to it. There should never be a "we have to record it again."

Not saving it externally. Everything is in the same folder. If I save it as a wave first, doesn’t that save everything into one channel instead of the 4 separate channels it was recorded on? If so, this doesn’t help me because I. We’d to be able to edit the channels jndividally.

It has recently been discovered that in Audacity 2.2.1, if you overwrite the current project (the project having been saved previously) using "Save Project As...", then data loss can occur.
This issue has been fixed in the soon to be released Audacity 2.2.2.

The workaround for people using Audacity 2.2.1, is to use "Save Project" (or "Ctrl + S") when updating the current saved project, rather than "Save Project As".

Correct. Best you can do is stereo that I know of.

I would still go to the effort to export in a standard sound format rather than save a live show as a Project. Projects for original work is not recommended.

I'm going to grab my coffee and take a step back. I'm not a Windows elf.

when updating the current saved project,

Doesn't that "step on" the original recording? Would it be a good idea to copy the original AUP file and _DATA folder to a safe backup location?

That is one heck of a Huge Bug. I would imagine almost all users use the "Save Project As" function because they want to preserve the original recording. With a bug this big 2.2.1 should be taken down until fixed or should come with a humongous warning so people understand that saving their work could botch the whole thing.

Thanks for everyone's time. I have no idea what to do next because saving it as a WAV, in the beginning, is not a workaround when you have 4 channels that need to be edited separately, and neither is overwriting the original file by simply saving because "Save Project As" doesn't work.

No, but you can make a unique show folder and copy the AUP file and _DATA folder into it. I personally would move the copy to another drive. Another variation is a ZIP archive of both file and folder.

Do Not change the names of either the AUP file or _DATA folder.

is not a workaround when you have 4 channels

Actually it is. The desperation method is make two stereo tracks and save them individually.

And just when wer'e getting all excited about this, how long is the show? Stereo WAV classic limit is 3 hours. Most times you can put up with the risk and save 6 hours.

That's the file size limit. The classic limit is 2GB and three hours comes in about 1.91GB. Most systems are fine with 4GB and that will allow you to manage six hours. I mention this because I have two stand-alone recorders of modern vintage that still insist on 2GB file foldovers—switching to a new recorded sound file at the 2GB boundary.
