MY SD card recorded NO data last night...(resolved)

I've got a simple question today. Need help with my SD card that you put in the machine.

I pulled out the SD card upon waking up (and was having a major leak as I woke up 7 hours after going to bed, but think I slept good).

When I opened sleepyhead and checked my SD card this morning, there was no data for last night.

I had pulled out the card to check the Data yesterday, which worked well, then reinserted the SD card in the Cpap machine yesterday afternoon.
Thought that's all I had to do but obviously something went wrong as the machine didn't record any data.

Anyone know what I did wrong?

I feel pretty good, not sure how long the leak lasted that woke me up. But was eager to see how the night went but last night is a lost
cause due to this major mistake by me.

last night was night 2. So I'm a newbie.

Did you lock the card and then forget to unlock?

How quickly did you remove the SD card from the machine this morning? If you didn't give it enough time to write to and close the files then it will be missing the data.

Also...when you inserted the SD card into the machine yesterday afternoon did you look at the screen to make sure the machine recognized the SD card...I make that mistake myself.

Some data is stored on the machine though...so put the SD card back into the machine and make sure it writes to the card and then try again. You may not have all the graphs but you should have summary data available.

Thanks for trying to help Pugsy....guess what? I'm an idiot.

I needed to open Sleepyhead, IMPORT DATA, and there it was. I skipped that part

It was a stupid mistake.

I had an AHI of 3.9

I woke up with major leak going on and a headache, but overall feel good. I'm trying to figure out the leak thing now.

Oh yeah, that import thing is kinda important but don't feel bad....I have done the same thing and sit there and wonder for half an hour where I screwed up.

I'd delete this thread but will leave it up for the next poor soul that does what I did, maybe it'll help someone?

Sleepyhead had no date for my session of last night, but ResScan did which means the data is on the SD Card. I don't understand but I'm also a newbie and there is a lot to absorb. I'll just use ResScan exclusively.
