100922 AC42 recording A42 became corrupted before it could be downloaded from the flash drive I used the chkdsk utility to find any data chunks that were still good. This was stored as FILE0000.CHK. That file was then opened in Cool Edit Pro and saved as a wav file. A42 was longer than C42, but upon listening and setting the cursor on the two files at calls/clicks it does appear that they starte at the same time. Therefore the files were spliced starting at their zero point. The last minute, which was not the same length in both files was left off. JW
