new SD card?

[k888]

Greetings,
If I use a new SD card, will it simply add new data to my OSCAR file, or is there a risk of deleting/corrupting existing OSCAR data?  I have a Mac.  There have recently been two nights (separated briefly in time) when OSCAR imports no data (not even a summary), even though the SD card was in the CPAP all night and unlocked, and I used the machine.  The OSCAR data seems to indicate I did not use the machine, even though I did.  The summary does not appear on subsequent days either – there is just a hole for that day.  I'm not sure whether the problem lies with the machine, the card, or me.  I would think a new card would be no problem, but better, in this case, to ask first.  Thanks, k888

Data is always appended to existing data in OSCAR. The Mac can be a problem child regarding allowing an app the permission to use removable devices. This can occur after a system update.

Thank you Crimson Nape.  I will use the new card.  I did just double check and OSCAR has full permission to access the desktop/documents/removable volumes.  I do tend to stick the card in before starting up my computer.  Maybe I will wait until everything has started up.  Fingers crossed it will all work.  I have gotten used to all the data and feel cheated when it does not appear.  k888
