ResMed S9 SD Card issue

[grizwilson]

    Recently when i turned the S9 on, it gave me a msg "invalid data" do you want to erase?, did not want to lose data, so removed card, started machine, re installed card worked fine, until the next night. So, put in a standard kingston SD card, all worked well. My supplier sent a new ResMed Card, same issue as original.... Since no data stored on new clicked yes to erase, all seems fine???? Going to take in for a check up, any thoughts or experience would be appreciated. I had never taked my card out intentionally, might have knocked loose changing filter???? no windows 8 or anything as on other threads...???

Since you,re not using any software, unplug the machine from wall outlet, wait for a while and plug it back
Action is required otherwise the machine does not start with this message displayed on the screen
If you click yes, you,ll loose detailed data as detailed data stored on the card. The machine store therapy and compliance data (for insurance reporting) up to 365 days and write this data on the SD card whenever SD card inserted

Before you do that, might want to download the data on your computer so you don,t loose any detailed data, lock the card before inserting it in card reader so nothing get written on the card and corrupt it, unlock before insert in the machine

I've encountered lots of problems with Resmed SD cards. Power interruptions seem to really confuse the cards.

As above, saying YES doesn't do anything to the data on the machine. Losing the detailed data on the card really isn't a big deal IMO.

As the others have said, losing data on the card is not a big problem. The machine will retain what's important for the sleep doc's and insurance co's use.

The fact that you have experienced this problem a couple of times without any apparent reason could point to a problem with the card reader in the machine itself. Or possibly even the logic board on the machine, although that is doubtful. In any case, keep an eye on it, and if it re-occurs you might want to investigate exercising the warranty on the machine.

Yes, it could just be crummy cards, but I doubt that too.

There have been a few ResMed machines with crappy card readers.

Are you taking the card out to get the data off yourself? If so, are you "locking" it before you put it into your computer? Is your computer a Mac?

Or is the machine doing this all by itself just with the ResMed cards? If that's it, then I'd vote for bad card reader. Either that or the DME has a batch of bad cards but then everyone would be complaining, not just you.

I just got a ResMed Auto 9. I removed the SD card to look at last nights data using ResScan. This worked great. However, when I put the card back in the machine it asks me if I really want to erase the data on the card. When I say no, it says to remove the SD card to start therapy. If I remove the card the machine will work fine but not record anything. If I say yes to erasing the data, the machine will record all subsequent data to the SD card. What this means is that I cannot view the data on the card without destroying it on the card when I put it back in. I read about "locking the card" what does this mean and how do you do it with the S9?

RE: JBall61

No problem.... Just let it erase the card. Once it does that, it will automatically write all the data back to it with the exception of the detailed graph stuff. That detailed stuff is kept on the card for only 7 days anyhow. So in other words a week from now it would drop off anyway. In the meantime you have it on the computer, and you have everything your sleep lab needs on the card at all times.

I predict you are using Windows 8.1. That operating system writes a stupid little file on the card when you stick it in the machine. That's what the Resmed is unhappy about. To avoid this in the future, set the "lock" on the card before you put it in the computer. But 5 months from now when you forget to do that, just let the Resmed have its way with the card and know all is in fine order.
