[Equipment] SD Cards and write-protect
#1
SD Cards and write-protect
When I first started CPAP therapy, I was running Microsoft Windows 7.  The warning in Sleepyhead & OSCAR to write-protect your SD card is absolutely needed for Windows users, any version I know of.  When my Windows notebook died, I went to a backup Windows 7 machine, then migrated everything to a Linux (Mint 18.3) unit.  As an IT professional, I had watched Microsoft's antics/insanity with Windows 10, and decided I would never trust my data or functionality to Microsoft again.

Over the years using Windows, I lost several SD cards to a failure of the write-protect slider.  It slides on a thin and fragile plastic rib, which can break, the slider can pop off, etc.  If anything happens like this, the card appears as permanently write-protected to any device, CPAP or computer.  I know its possible to use tape to fake the slider, but I was never willing to risk the tape coming loose and getting caught in a card slot.  So I have a collection of useless SD cards I'll probably throw away some day.  

However, now that I am running Linux, there is no need to change the write-protect slider at all, as Linux does not attempt to write anything to the card when it is inserted for reading.  I can't speak for Mac users, as I have never used that OS in a meaningful way.  But Linux users can dispense with the write-protect setting, and extend the life of their SD cards by doing so.

And the OSCAR team can consider removing the warning for the Linux builds.

RE: SD Cards and write-protect
It’s only the Resmed S9 that’s affected with this issue the warning has been removed from other machines, I don’t really see the need to remove the warning for one build of OS.

I switched to the FlashAir card w/ FlashPAP to download. I haven't touched the card since I started using it.
