Another ResScan Question

I was using the SD card that came with my S9 Elite (a whopping 512mb). After reading here how to download all the detailed stuff, I was happily doing this every day until last Thursday.

Then - O-Oh! SD card shows 96% full. Soooo.... it would download the basics but no detailed graphs.

I bought a 4Gb replacement SD card and filed the 512mb one to dutifully send back to the DME, HOWEVER I can't get the detailed graphs for November 12th and didn't want to go messing around with things until I asked the experts here.

Would so much appreciate some help on this - whether I can or can't access the detailed info for this date, and if yes, then how the heck do I get to it??

Many thanks,

Two things

1) Why did you just download the summary and not the detailed data from the initial card? Your detailed data is on the card waiting to be read into rescan. Downloading the basics just because your card is 96% full makes no sense. Also as i understand it the card will not get full and stop recording, it goes through cycles of overwriting the oldest data. You were downloading data into ResScan everyday i'm not sure why you needed to purchase a 4GB card.

2) Which card has the nightly data for November the 12th? Using that card you can try and download again and select overwrite instead of discard for duplicates. If that does not work then you can try right clicking on the orange bar for the Nov 12th in the data browser and select delete session. Restart ResScan and try a download with detailed data.

Because the card wouldn't physically download the detailed data once it showed 96% full, no matter how I tried. I'm wondering if I'm checking a wrong option when I overwrite or discard (I select overwrite). I bought a 4Gb card because it was inexepensive and the DME wants the other one back.

Both cards now have the nightly data for November 12th, but both say there is NO detailed graphs available for that night. I'll try as you suggest when I get home. I didn't want to start experimenting in case I deleted stuff I want to keep.

Thanks a bunch Uncle_Bob

UGHHH!! UB - I tried everything you suggested, using both SD cards. I tried the original SD card first, and that wouldn't even give me back the deleted session for Nov. 12th, but got it back with the new card. I actually have 2 days that there are no detailed graphs for - Nov 11 & 12.

I guess both these dates are lost or floating around inside the machine somewhere.

My last suggestion is to create a new patient in ResScan and try and download the data against that new patient.

Thanks Uncle_Bob - will try that tonight.

The detailed data will only exist on both one card, that will be the one that was inserted into the S9 during the night in question.
If you purchased a new card and inserted it then it will have copied summary data only, no detailed data.

No, they are not floating around in the machine somewhere. The high resolution data file, date+time+BRP.edf, is the only one that has the flow data in it. It is written to the card as the machine runs and the flow data is not stored in the machine. There are only seven days of BRP files on the card, never more. That is hard coded into the S9 firmware. Look at your card directory and see if there is or is not a BRP file there dated the 12th or 13th. If you went to bed w/ the CPAP before midnight the file for the session for Nov 12 will be dated the 12th. If you turned your machine on, or off and on, after midnight, the date will be the 13th. A new BRP file is written every time the S9 is turned on and off. An S9 day goes from noon to noon and carries the date of the beginning afternoon. To be more clear, Resscan session date is noon to noon. The date stamp on the file is the actual clock date.

Now, as for your card being 96% full, that can't be. 365 days of summary data, 30 days, the max, of detail data, and 7 days of hi res data will only add up to about 30, maybe 40 Mb, way under 512 Mb capacity of the card. I think that somehow or another the directory of your card got corrupted and that's why you got the 96% full message. Did you by chance remove the card from the S9 immediately after turning it off? That may have done it if you did. If not that you may have a defective card.

I recommend anyone who is serious about reviewing their data always copy the card contents to a folder on your computer before you open up Resscan. Make a new folder for each time you copy the card contents. That way you can copy the files back to a different card, or back to the same card after formatting, or whatever. The S9 doesn't care if the files have been copied back to a card, as long as the directory structure is the same. Also, as others have recommended, to be extra safe lock the SD card by sliding the little lock on the side before putting it into your PC card reader. That will prevent the PC from messing with the card. Of course, if you have to format the card, or write to it, it has to be unlocked. Be sure to unlock it before you put back into the S9.

Hmm, you make a good point - I did in fact go to bed after midnight on both the 12th and the 13th, however I do this every Friday and Saturday nights and I have the data from the other weekends.

I'll do as you suggest also, when I get home from work.

Thanks much!

Thanks for all the help. I checked the BRP files on both cards, and neither of them has Nov. 12 & 13, and one of them doesn't have the 11th either, however all dates are saved in ResScan, but I have no Detailed Graphs of 11th, 12th or 13th.

I printed out this thread and left it for 2nd shift hubby to look at (but he only had one SD card as the other was in the machine as I was zzzzzz'ing).

He didn't leave me a Eureka! note, so guessing he didn't have any joy either. My presumption is that I should just forget about the lost data and just keep using my 4Gb card.

You might as well forget about the lost data. If you don't find those files on the card the data evaporated to the great bit bucket in the sky! You're probably missing the PLD files for those dates. Those have the detail data, not flow, in them. They're kept for 30 days. The reason you see the dates in Resscan is because the summary data is kept in the summary.edf file in the card's root folder. When you look at the date list in Resscan you'll see an additional icon for days with detail data. Also don't just recklessly swap cards between the two machines. That'll wipe out data in an instant. When you put a strange card into the S9 it'll format the card!
