What versions of SleepyHead and ResScan are you using?
If it's not SleepyHead 0.9.8-1, download that from here:
Thanks for the link. which I upgraded, but did not help. Maybe this is just a fluke ? Before today all was well, still have charts of history. I will try in the AM again. The ResMed software is 5.3
Oh BTW new software is nice.
I have the same machine. When I first got it, it would not record the high rate data.
I had to disconnect power for some minutes; then reconnect; and it worked.
Summary data is kept on the machine; The data card records 30 days of detailed data and 7 days of high sample rate data.
Once lost from the card, it cannot be recovered as the data only lives on the card.
A defective card is a possibility.

There is a "sleep quality" setting in the provider menu that has to do with AHI display. It should be set to on to display data.
In theory, it only affects the LCD display, not the SD card data, but check it.
Get the free SleepyHead software here
for information on the main alternative to CPAP.
If it's midnight and a DME tells you it's dark outside, go and check it yourself.
Thanks to archangle, justMongo,sgearhart, for all suggestions,tried each but nothing changed. I opened the file this AM and info. was there for today. Info for the 6th is void except for summery info. Anyway seams to be ok for now.
It's possible the SD card was not fully seated in the machine at the time the detailed information is written, just as it is turned off. I have forgotten to put the SD back into the machine a time or two. It records summary information, but the details for that day never appear. As long as the card is properly in-place from the beginning of a session until the machine stops writing to disk at the end of therapy, you will probably have the detailed data.
