Were both of these new SD cards? That's what you need for your machine. You can get a 32GB card (not more than that) at most stores, Walmart, etc.

Rodeo,

Did you have the SD card in your pap machine while you were sleeping? If not, you won't see detailed data.

Many of these SD cards have a small switch on the side that alternates from 'locked' and 'unlocked'. The card will need to be 'unlocked' to write data from the machine, so just make sure that's still the case.

SD card was unlocked and in machine at nite. original card that came with mach downloaded daily for 2 weeks with no problem suddenly I got message there was no data for nite. I put in new sd card all data was transferred to new card with no data for nites same as original card.

OK, here are some things to try.  It may point to where your problem is occurring.  First, power cycle your CPAP.   Allow about 30-seconds before reconnecting the power.

Now let's check the SD card.  This will not require OSCAR.  Insert the SD card in your PC's card reader.  Copy or create a text file, storing it on the SD card.  The contents and size don't matter, we just need a file.  Also, this file will not affect any data on the card.  If all goes well, and the file is on the SD card, try opening to read it.  If successful, then the card should be good.  You can delete the file off of it, too.

One last thing to try. (I'm sure I'll think of something else about 30-seconds after I press the "Post" button.)  Let's make sure OSCAR is looking for the data at the correct location.  Start OSCAR.  Go to File > Preferences >  Import > Memory and Startup Options.  Deselect Import without asking for confirmation, press "OK" and exit.  Select the CPAP Importer.  When the confirmation screen appears, choose Specify.  Navigate to your SD card and select it. . . Just in case there was a bad path being used.  

If the above corrects your problem, then you're good to go.  If your problem still exists, then I would suspect a bad SD module on your CPAP.

Please report success or failure.
