TDMS error -2503. Is seemingly corrupted file able to be recovered?

[alekennedy]

Do you know the possible causes for tdms file corruption?

Sorry, i´ve got no idea. The VI solved my problem but I´ve got no idea what was corrupted inside.

Thanks to Yongqing Ye, this recovers my TDMS data, it didn't closed while the software is crashed. Saved me a lot of effort without redo the test again.

I had the same problem with a TDMS file. Deleting the index file did not work for me.

My approach was to use the advanced open and advanced close function. This worked fine for me.

Both with default values.

Hey, same thing happened to me and in 2022! but this vi totally fixed the problem.  Thank you!

Just fixed a file for me in 2025, thanks!

(BTW- can anyone explain how this fix works? I have a few hundred files and this is the first time it's happened to me, and I don't relish the idea of learning the deep details of the TDMS file format to fix a bug that hasn't happened to me in the several years I've been using this program to make TDMS files.)
