It will help to slide the "write-lock" tab from read-write to read-only before importing your data into SH. When you take your SD card out of your machine, on the upper lefthand side of the card there's a sliding tab. When it's in your cpap, that tab resides at the upper lefthand part of the card, where I'm referring to the side with the cut off corner as the top. When you take the SD card out of your cpap, just use your fingernail to slide that tab towards the word "lock" or a lock symbol, whichever you card has. After you've read your data with SH and ejected your card, don't forget to slide the tab back to make the SD card read-write again. If you watch the display on your cpap, it'll remind you if you've left it read-only. And you can take the card out, slide the tab, and put the card back in.2kittymom wrote:I would have loved to have been able to check the cpap data card on Sleepyhead or Redmed, but I seem to have botched something up, and can't get any data. Then, when I put the card back into the machine, it makes me erase it or it won't work at all. Do you think I ruined the data card?
You haven't ruined the SD card if what I think happened is what happened, you've just lost some detailed data. Your cpap machine keeps the data stored inside of it, and when it senses something wrong with the card (like your computer wrote to it), re-writes it's internally saved data to the card and everything's good again. Just the latest detailed data is saved, so you'll lose the rest of the detailed data that was on your card.
So no harm, other than some data that you most likely don't look at very much.
