[CPAP] ResMed not collecting data

[sonicboom]

See my post in another thread about possible manufacturing defect in the recording functions of the A10. It records for awhile then stops........

First I would reformat SD card. Possible that the data on the card got partially written or corrupted when the power went out unexpectedly.

If you can still read the card on your computer then pull all the data that you can into sleepyhead.

Next use the computer to reformat SD card.

Now insert it back into the CPAP machine and let it rewrite the historical summary data. Next write protect the SD card and see if you can read it on your computer.

If you can read the data on the computer, then chances are good that the card is now OK to start collecting new data. And we have established that the CPAP machine can write data.

Run a ten minute session and see if it writes the detail session data.

If yes then you are back in business

If you can't read or format the card on the computer then buy a new 2GB SD card. Under $10 online, ~$20 local store.

If the card is okay and the CPAP machine can't write to it then it's a faulty machine, and time to call the DME for warranty replacement.

So I don't need an actual ResMed card? There's no specific data on the original card that the machine needs in order to work?

If that's the case, I have plenty of SD cards around (16 GB to 64 GB), and I can use one of those.

Thanks so much for the info!!

Resmed will spin you a yarn about only using their branded cards but that's - shall we say - a case of marketing getting in the way of the facts. The older S9 machines apparently wouldn't work with a card larger than 2 gb but I understand this limitation doesn't apply to the more recent units. If your 16 gb card won't work, get hold of a 2 gb and try that.

Any blank SD should work. There is no "factory data" on the card that is not written to the card by the machine.

Anything bigger than 2 GB is overkill. Unclear if the CPAP machine can read & write beyond 2 GB, but in my experience with phones and cameras most devices will accept a higher capacity card but not use any more than the device's capability. YMMV.

Never tried a card greater then 2 GB on my A10, so if trying a spare 64GB card doesn't work you might need to get a 2GB one. It will either work or it won't... No harm in trying. You will want to let the CPAP machine format the card so the file system isn't written to space the machine can't access.

Worth a try if you have spare ones. Worst case you go buy a 2GB card.

Thank you ALL very much! It's so great to be able to ask questions and receive knowledgeable answers without having to deal with manufacturers and their ummmm... effluent. LOL

If your 16 gb card won't work, get hold of a 2 gb and try that.

A 16 gigabyte micro sd with an adapter for the SD worked fine in my machine. My WIFI enabled SD card is also 16GB and works fine too. That much space may be overkill but SD has a limited (very large) number of writes and the more space there is the longer it will be until that limit is reached.
