Two-hour mix of music and speech.
Approximately 20 channels.
After finishing editing exported to mp3
Shut down computer.
Nowhere in there did you save the project. Did you, or are you emergency rescuing the project every time you do this?
Shut down computer.
Started computer four hours later.
And that’s exactly what you did, right? Cold Start.
There is one virus protection software product that gets it in its craw every so often to “help you” by eating some of those “dangerous” project files.
How long have you had the SSD? They do develop leaks after a while. They’re not perfect (although they do very well). What happens if you do a drive check, or integrity check or whatever it is in Windows. If Audacity exits cleanly and the show just doesn’t open right after a restart, the data went somewhere. I bet the drive fails.
You can’t cause the problem, right? You can’t get up in the morning saying: “Today I’m going to lose some files.”
I saved the file in a folder on the C drive under “Public Documents”. (I access the folder later to transfer the mp3 to my older computer.)
I never did an emergency rescue, the project opens fine, and I don’t see any messages indicating that I need to do an emergency rescue.
So I suppose what I am doing is “cold start”.
Which virus program are you referring to that may be eating my sounds?
I had the SSD since June 2014. I heard about the leak issue some years ago from a friend who was working for Sandisk. They were developing an algorithm to spread out the read-writes.
I will do a check of the drive, see what I come up with.
As for 2.0.5 versus 2.1.1, I found out about this earlier today when I was starting my post, and downloaded and installed it
saved the file in a folder on the C drive under “Public Documents”. (I access the folder later to transfer the mp3 to my older computer.)
I never did an emergency rescue, the project opens fine, and I don’t see any messages indicating that I need to do an emergency rescue.
You keep using the wrong English words.
“I got to the end of my editing, File > Saved the project which produced an AUP file and a _DATA folder. Then I File > Exported an MP3 of the same show.”
That’s what’s suppose to happen. Is that different from what you’ve been doing?
You said something else, too. Is your C: drive mounted as a network drive? Audacity doesn’t speak network very well. It doesn’t understand network delays and collision management. That might be where your data is going.
“Cold Start” is bringing up your computer from a power-down condition.
Turn off Norton’s “Windows temporary file cleaner” or File > Save Project As… before recording. Make sure you save to a folder that does not have “temp” or “tmp” in its name.
Alternatively open Edit > Preferences… from the Audacity menus, go to the Directories section, and type a folder name in the box that does not have “temp” or “tmp” in its name.
So “Opened the project” meant that you had already used File > Save Project… - yes?
Where are the missing parts shown as red - in File > Check Dependencies…? If missing imported files are the problem, you need to put those files back in the paths shown in the Dependencies Dialogue. To avoid losing imported WAV or AIFF files, make sure in Import / Export Preferences that “When importing audio files” is set to “Make a copy of uncompressed audio files before editing (safer)”. Then If you see a warning dialogue about uncompressed files when you import, just click OK. Don’t change the setting in that warning back to “read… directly”.
Otherwise, did any time elapse between between export of MP3 and saving the project? A file cleanup or anti-virus app could have deleted some of your temporary files in that time. It only needs a second or two to do it.
Also after opening the saved AUP file, please open Help > Show Log…, save the log and attach it. Please see How to attach files to forum posts.
