I've been having problems getting data logs from my 4500 unit. With the previous software loaded into it, I could dump the data logs, but even with the data dump set to maximum time, it would only dump about 15 minutes of data, and then write seemingly garbage data to the file.

After updating the software to the latest version, I get the message "Data Not Available" when I try to dump the data log, even when I know there should be data stored in the system. I did some taxiing/run ups and still there is no data.

I'm not sure what I did, other than update the system code, to cause this. Could I have accidentally deleted a necessary file on the data card?
