Problem with ResScan 31302 (3.16 SP1)

[NateS]

I'm very pleased with Sleepyhead and I'm trying to learn how to read and interpret all my data in it.

However, whenever a post I read discusses and displays a member's ResScan chart, I find it hard to interpret and compare their findings with mine, so I downloaded 31302_ResScan_3.16_SP1.exe and installed it.

First I installed it in my Windows XP Professional virtual machine in Parallels 7 on my MacBook Pro. As advised, I avoided requesting the installation of the 3 proposed drivers. It installed just fine, and I had no trouble creating a client and opening my client file, but when I select "Download data" I get: "There are NO devices available for downloading data." I tried inserting the SD into my built-in SD port before, during and after with no difference. ResScan does not see the SD card removed from my S9. This is the same SD card from my S9 that SleepyHead has no trouble reading data from.

Thinking that it may be a quirk or deficiency in my virtual software, I slid down to the other end of the sofa, opened the Dell Inspiron running Windows Vista, and again downloaded 31302_ResScan_3.16_SP1.exe and installed it on the Dell. As advised, I avoided requesting the installation of the 3 proposed drivers. Once more - It installed just fine, and I had no trouble creating a client and opening my client file, but when I select "Download data" I get: "There are NO devices available for downloading data." I tried inserting the SD into the Dell's built-in SD port before, during and after with no difference. ResScan does not see the SD card removed from my S9. This is the same SD card from my S9 that SleepyHead has no trouble reading data from.

Is there something I'm overlooking here? Is there some reason the ReScan software appears to install and run on both machines, but can't see the SD card?

Any advice from you more experienced veterans would be very much appreciated!

Highly likely.... there are a whole bunch of users here using it successfully on a variety of Windows system versions.

"Highly likely"??? Haha

Could you spare a poor fellow a suggestion or two?

Well, you haven't said a single thing about whether the SD card is visible to either version of Windows.

Does Windows know that the S9 SD card has been inserted in the SD card slot (whether or not ResScan is running)?

Can you look at the FAT file system directory of the SD card with Windows?

IF THE SD CARD READER AND SD CARD IS NOT VISIBLE TO WINDOWS, IT WILL NOT BE VISIBLE TO RESSCAN.

The ResMed SD card is not visible to Windows - not on the virtual machine and not on the native Windows machine.
Other SD cards I insert into the built-in SD card readers are visible to Windows on both machines.

Is there some special non-Windows formatting that my ResMed S9 uses which can only be seen from within the ResScan program?

Apparently, there is nothing wrong with the built-in card readers on both computers, and Sleepyhead reads the data off the SD card just fine.

Could the SD card not be read because I lock the card each time I remove it from my S9 and only unlock it when it returns to the S9?
(No way am I going to insert this card unlocked to either computer.)
If that is the problem, that is just weird to me. I suppose I can try duping the sd card and inserting the dupe unlocked.

That may well be, and I hope someday soon to join them, but it is also true that a google search for "Resscan can't see sd card -rescan" etc. turns up many many pages of hits of another "whole bunch of users" reciting the same problem and no solution, some even back to this board.

Okay, I solved it myself by dispensing with the sd readers on the two computers.

I formatted a flash drive in FAT 32 and copied all the data from the sd card to the flash drive.

ResScan immediately opened a window reporting the discovery of data from my S9 VPAP Adapt and let me associate it with a patient file.

And away we go …now to study and learn how to use and benefit from the ResScan info and graphs and charts etc.

My new routine will be to regularly copy from my (locked) sd card out of my VPAP each time to this flash drive.

Very apparently there is ineed something wrong, but since you seem to have made up your mind what the problem is, I'll leave you to it.

Never insert an unlocked ResMed S9 data card into a Mac. It's been reported that the Mac will write some sort of index file on it and the S9 will pitch a hissy fit.

It's also been said that ResMed uses some bastardized data formatting on the card. It usually looks OK to most Windows PCs, but there are some things that really aren't kosher about the way it uses the card. It's usually a case of the S9 machine not being willing to use the card after the PC has touched it, but maybe there are some problems going the other way as well.

Yes, I stand by my conclusion and I'll tell you why:

In addition to copying the data to a flash drive, I also freshly re-formatted a spare SD card I had lying around, I copied all the data also to that SD card, and that 2nd SD card shows up just fine in Windows Explorer under a drive letter, and when opened it reveals all the same contents in Windows Explorer just as does the flash drive, but ResScan can't see that SD card either!

Conclusion: there is something non-standard about the formatting of the sd card which comes with the S9, and when presented with an SD card, ResScan looks for that formatting.
It may be visible on some Windows machines but not all.

And also keep in mind that Archangel hates ResScan... maybe because he can't use it on his PR machine. Works great with my S9 and Windows 7 machine!

Yes there is.

You need the SDFormater software (free) to format SD cards (especially those older 1 GB ones)

Thanks very much for that information, Steven.

Following your advice, I downloaded and installed SDFormater, re-formatted my spare SD card, re-copied my S9 data to the spare card and voila! - now ResScan sees the data and downloads it from the spare SD card just as it did from my flash drive.

So that gives me another option as to a target to which you copy my S9 data so ResScan can read it.

And I guess that it also provides further support for the notion that the ResMed S9 does not use an industry standard method for formatting its SD cards?

"The SD Formatter was created specifically for memory cards using the SD/SDHC/SDXC standards. It is strongly recommended to use the SD Formatter instead of formatting utilities provided with operating systems that format various types of storage media. Using generic formatting utilities may result in less than optimal performance for your memory cards."

Interesting. I've never had a problem with Resscan reading an SD card that was formatted on my PC with XP. The only thing I've ever seen non-standard with the S9 card is a directory entry for a journal.dat file which references a sector near the end of the card. Resscan doesn't care about that file. Otherwise it's a standard FAT32 file system, at least according to WinHex. The only thing Resscan cares about, in my experience, is that the CRC files are correct. I use a Dynex (BestBuy brand) card reader connected to the end of a USB cable.

Other USB reader software will muck things up. I think it was a driver to read an LG phone that completely stopped Resscan from reading an SD card. Got rid of the LG driver and all was OK again.

Now that's very interesting! I have an LG Optimus, and I have on occasion had it connected to my Mac with USB Debugging turned on for development. It's probable that LG drivers were installed when running adb under Android SDK.

(On the other hand, the LG has never been connected to the Dell, and ResScan on the Dell couldn't see the S9 SD card either.)

There is nothing non-standard about the FAT file system written by the S9, so if your computers won't recognise the file system, then you DO have an issue with something installed on your computers.

and when presented with an SD card, ResScan looks for that formatting.

That is related to where the S9 flow generator expects to see a file, but has nothing to do with the way the FAT file system presents to a computer.
