Have read the card many times, data is not erased. Locking the card is always a good precaution.
If everyone thinks alike, then someone isn't thinking.
Everyone knows something, together we could know everything.
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.
As always, YMMV! You do not have to agree or disagree, I am not a professional so my mental meanderings are simply recollections of things from my own life.

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.
