Recovery important measurement data from raw .cdpg file of Citadel database

[yyhk]

We bought NI DAQPad-6015 to acquire data in a very important experiment.  During this experiment, we used VI logger Lite 2.0.1 to capture those data and the software automatically save those data in the specific Citadel database.  We totally got about 600M data and would export them from Citadel database for further data processing.  Unfortunately, for some accidence, some files of Citadel database such as .cdin and .cdih are damaged, all the raw data in the .cdpg format deadlly stored.  The experiment is very important.  Would you  please help me to recovery them.  Thanks!

Since .cdin and .cdih files are damaged, some important information is missing, it is harder to recovery them.  However, would you please tell me some information about the Citadel database.  Is it possible to program to write  .cdin and .cdih files and recovery tha raw data?  The two .cdpg data files attached by this letter is one time acqiured data using N samples mode in VI logger, the sampling rate is 20, 000 and sampling number is 300,000.

Would you please help me, thanks again!

Hi yyhk-

Unfortunately there is little that can be done to retrieve the historical data from your db;  all files are integral to the Citadel format and the remaining file is not in a format that can be retrieved.  I'm afraid that your data will not be accessible unless some backups of the original files are available.

Thanks-
