I have a CR1000 with a NL115 and 2GB Campbell CF card. I accidentally reprogrammed the logger before downloading data. Is it possible to recover old data from the CF card after the datalogger has been reprogrammed?
If your CR1000 was running one of the later OS revisions, by default it would have left the files from the old program on the card. Pull the card and copy files to a PC to check the contents.
Erase the card before putting back in the data logger so the new program has space to save data.
