Sleepyhead shows a normal night for 5/15 (last night) but imports nothing for 5/14.

The S9 LCD Sleep Report:
Period One Week
Days Used 6/7

If I understand correctly, that means the S9 summary data is missing one day from last week.

Like PollCat, I suspected that the card was not properly seated but as robysue said "That would cause no data to show up in SH. But it would NOT affect the data on the machine's LCD provided you looked at the LCD data before noon on the S9's internal clock." Also, I habitually observe the S9 message "reading SD card" to confirm that I have unlocked the card and inserted it fully. So I'm fairly sure the card was seated.

Hmmm...I'll wait for an opinion from our alien watchers.

Well unless the machine had a major brain farc, the summary data will still be present. Once you plopped the sdcard back into the machine, it will have written it to the card. But without the detail stuff, Sleepyhead will simply elect to not look for it. You can see it with the Rescan software if you have installed that.

The data for 5/14, both summary and detailed does not exist in Sleepyhead, ResScan or on the S9 LCD Sleep Report. I was counting on you to give me the alien invasion explanation. I think May 14th was absorbed by a ripple in the time/space continuum. At least at my house it was. I'm pretty sure I went to bed that night.
