Does reading the data card erase the data?

[Marnid2014]

My DME guy told me that if you remove the card and read it, it erases all the previous data. Huh? It's only a sim card, why would that be? I was going to read mine again today, but now he's got me worried. I am using the Sleepy head software. Anyone? I know I have to give the card to the insurance company at the end of the 30 day's.

No, that's ridiculous. In SleepyHead's case, it doesn't even touch the data or modify it. It copies from the SD card and saves it locally to the Sleepyhead folder and into the local Sleepyhead Database.

If you have any doubts, slide the data lock tab on the SD card. It prevents writing/erasing the data.

Have read the card many times, data is not erased. Locking the card is always a good precaution.

What can and does happen is if you put the sd card into a windows 8.1 computer it will do something to the card. Then when you put it back in your Resmed, it will insist on formatting the card.

If you "lock" the card before you put it into the computer this will not happen.

This has nothing to do with Sleepyhead, it's just something that Windows 8.1 will do for you.

It's not actually the end of the world though. The card only keeps a few days of detailed data on it that cannot be replaced when it has been reinserted into the resmed. So after a few days you would never know anything happened.

The summary data will always be rewritten to the card by the resmed. It's just the detail stuff that's a concern.

Hi Marnid! No, the DME is either ignorant or trying to keep you from taking control of your own healthcare. My Respironics machine has the same type card your ResMed machine does. I've been using Sleepy head for years now but just the other day I loaded up the latest version of the Respironics software called Encore. I tried to use the prior version a couple years ago but it would not work for me for some reason. I plugged in my card and 2 years worth of daya went from the card to the program, so no, Sleepyhead does not erase your card. To be safe with the new Windows 8.1 if you are using that, just slide the lock tab as suggested. Not a big deal.
Good luck!

Windows 8.1 formats the card to the NTFS file system. The S9 wants it in FAT32 format.

Just throwing some info out there. I have a PRS1 460 and am running Win 8.1 Pro. I read my SD card from the CPAP machine almost every day and never have "locked" the card. Win 8.1 has never written anything to the card and it's never reformatted the card. My CPAP machine has never given me any kind of warning or error message when reinserting the card.

Now, having said all that, I highly suggest that you do lock the card just in case.

Hi Marnid2014, welcome to the Forum!
Thanks for asking this question as it has been a concern of mine. I have been told by the person I am hiring from not to read the card. BUT of course I didn't listen to her, I listened to the good people on this forum and I downloaded SleepyHead.
Your question has always been at the back of my mind though, thinking I will take the machine back and there will be no data available.
Anyway, all the answers you have received have put my mind at rest.
I just don't understand when some people have said to 'lock' the card, to make extra sure we don't lose information. I'm not sure how to lock it.

There's a little slide switch on the left side when looking at the top of the card with the contact area pointing away from you. You slide that switch toward the end of the card to "protect" the card from being accidentally written or formatted.
