OSCAR displaying summary only for 13 out of 16 days imported

[EnigmaOfSleep]

I last imported my OSCAR data on the morning of October 17th (data up until October 16th). After the import was complete and I closed out OSCAR, I immediately ejected my SD card and put the card back in my machine and used it as usual. I then imported data today and everything from October 17th to October 29th is summary only. October 30th until last night has full detailed data. The SD card has not been touched from October 17th until today unless it was somehow bumped and then bumped back in without me realizing but that seems unlikely. The SD card was removed at least 1 hour after I got up each time so it shouldn't be an issue of the machine still writing data either. 

I've already tried purging and reimporting the data and that didn't fix it. I also tried rebuilding the CPAP data. My SD card is nowhere near being full. It's a 4GB card and it has over 3GB free on it. 

What could possibly be causing this and is there anything I can do it fix it? 

In case it's relevant: OSCAR software version is 1.2.0. Machine is Resmed AirSense 10 AutoSet. SD card is a Transcend 4GB Class 10 SDHC, I've used this card for years now with no issues.

I would strongly suggest that you upgrade to OSCAR v1.5.3, the current release version. This may correct your problem.

I didn't realize there was a new version. I checked via OSCAR and it said I had the latest version. I just downloaded and installed the new version. I purged all data and reimported and still have no detailed data on those days.

If your card as in your CPAP during those nights, then it may be time to replace the SD card.

It was almost certainly in the machine all night for all of those nights so I'll go ahead and replace it. Thank you for your quick responses.

Just had the same issue with Oscar v1.5.3.

Saturday night was summary only.  Last night caught everything and good to go for all the graphs.

I have de same problem. I have de new OSCAR version and I put a new SD card. No difference. I now get only the summary report. Can't get the graphs anymore.

I found a way to go around this problem..... simply had to select MANUALLY the drive where the card is located instead of simple saying YES to the proposed drive.
It's the same drive that the one that is proposed but for an unknow reason when selected by default I have only the summary and when I select the drive manually everything is there!  Computer software mysteries...
