I use Dream Station 1 with foam removed.

I've been using for years and my AHI is usually around 2, so I don't regularly download the data. Last download was 60 days ago. I've been using this SD CARD since 2018.

Yesterday I tried to look at the data on my SD CARD and I got the following error message from SleepyHead:

Error Message from Sleepy Head: "Couldn't find any valid CPAP data"

I looked at the data on the SD CARD and it appears that it is still being updated with current data from last night.

So, I downloaded OSCAR and tried reading the data, but I got this error message:

Error Message from OSCAR: Already up to date with CPAP data"

Yet when I look at my data in OSCAR, the last day it reported was June 2022. Last day SleepyHead reported was November, 2022.

I ran windows diagnostics on the SD Card and it reported that the SD Card was good.

Just in case, I am now using a new SD Card.

Anyone have any insight into this problem ?

thanks, Doug

That is puzzling. Are you saying that in SleepyHead you cannot see any daily report data and graphs since November 2022?

yes, but that was approximately the last time I downloaded data so it appeared to work fine last time I downloaded...

Another thought. When you are in the Welcome screen and click on CPAP Importer it should bring up a small window. It should automatically find your SD card and the data. Perhaps it has gotten confused as to where to look. You may want to try manually pointing it to the SD card drive number.

I did this and tried viewing from all the subfolders. - did not work. I tested a new sdcard last night and it worked fine and i was able to download this one night of data.

Sounds like a bad card I guess. Not sure why it would test ok from your computer.

I had an issue where nothing was recorded on my machine a few nights ago. I did a full format (FAT 32) of the card and it has been OK since. Not sure if it was that I didn't have the card fully in, or if the reformatting cured an issue.

Phillips encrypted the data on the DreamStation 2. OSCAR has since been updated to decrypt that data.
