Accidentally deleted data from SD card, is it still on machine? - theredheadsaid - 07-22-2022
So I've been using CPAP on my Resmed Airsense 10 with "card to cloud." Every morning I get up and upload the data from the SD card to a folder on my computer then up to OSCAR/SleepHQ.
Well this morning I must have been half asleep, because before I knew it, I was copying files FROM my computer TO THE SD CARD. I hit CANCEL part way through but the damage was done. I tried to hit command Z but it didn't do anything.
DATA RECOVERY: I did use a free utility to try to look at the deleted data on the card, but I didn't see a datalog folder with the code/date from yesterday, so it might have been overwritten. It costs $89 for the "upgrade" to actually recover any files and I don't have that extra money at the moment.
Now, luckily Sleep HQ has a data download, so I can export that from yesterday morning (so I'll only be missing data from last night).
Here's my question: I can see on the ResMed machine that even with the card out, it's showing my data from last night. Let's say I put my card back in, with all data except last night's. Will it then fill it the data from last night? or is that gone forever?
I'm in 100% compliance so far with my CPAP use so I'd hate to lose that whole day of data. But I've been using more than 4 hours per night usually so maybe it won't matter?

Hi theredheadsaid! -
Only the summary data is stored without the SD card. If you have been copying your SD card daily, then you only lost last night's detailed data.

If you don't have the card in for a night, the data is lost basically. It only records basic data back to the SD card. Must be because the machine itself doesn't have enough onboard memory to accomodate.

Sorry, Red, the machine does not keep the data onboard. I think your best bet is to restore as best you can from Sleep HQ and then add in the partial data from your machine for the most recent night. Your machine has captured the AHI and other indexes but you will be missing the data on flow limits and the actual machine pressures -- just for one night. The long term trend data should be valid.

Clownbell - According to Resmed, the S9 maintains 30 days of detailed data on the SD card. The AS10 doesn't have a limit. Without an SD card, the AS10 will store summary data for up to 365 days. Is this incorrect? How else can it provide the onboard option of reporting the following time intervals, 1 Day, 1 Week, 1 Month, 3 Months, 6 Months, or 1 Year?

CrimsonNape is correct. 365 days of summary data is stored internally on the AS10 series. It will be written to a new SD card when it is inserted.
