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
