SD Card Size
Hello All, I am a longtime CPAP user (I used to be on this forum a loooonnng time ago) but just discovered that Sleepyhead is now Oscar and works with my Chromebook!  I have a simple (I hope) question to start with:

I've only had a new Dreamstation for a week and it did not come with an SD card (it has a modem instead?)  I did some searching here today and read some posts that seemed to indicate that a smaller SD card is better (less than 32 GB) and a bigger one might not work, something about speed? 

I'm hopelessly outdated in my techy knowledge and I don't want to do anything to mess up the Dreamstation. I picked up a 64 GB micro SDXC UHS-1Card with Adapter at WalMart the other day and after reading all this I suspect I kind of overdid it (bigger should be better, right Smile).  

Also, I do have a ResMed SD card that I deleted all the info from. Would it, by any chance, work in the Dreamstation?

RE: SD Card Size
The ResMed card will work in the Dreamstation, although the Dreamstation may want to reformat the card - that's OK, let it reformat the card.

OSCAR currently works on Intel-powered Chromebooks, and the Wiki has some hints about setting it up. If you have any questions about getting started, start a new thread here, and we will follow up.

If you have an ARM powered (MediaTek?) Chromebook, that version is in testing, and will be available in the next release.

RE: SD Card Size
Thank you!  I put the ResMed card in the Dreamstation and it didn't spit it out. Actually didn't do anything but accept it so I assume all is well. Now I can start working on getting Oscar going.

RE: SD Card Size
It's not the speed of the SD card, it's how it's formatted. SD cards from 2GB to 32GB (SDHC) are FAT32 and are compatible with most machines.
Any SD card over 32GB (SDXC, SDUC) is exFAT and may have compatibility issues with CPAP machines which may lead to corrupt data.

My original ResMed SD card was only 4GB. A years worth of my machine data is just under 1.5GB so a 32GB card would hold many, MANY years of data.
