OSCAR and SH won't read SD card after Win7 to 10 upgrade

[FortCollinsSleeper]

OSCAR 1.1.0 downloaded 5/9/10 as replacement for Sleepyhead, which was lost during Win7 to Win10 upgrade last month.
Software loaded and Profile entered OK.
 
I put my SD card in and I get:
   
To which I answer "Cancel"   (If I say format Disk, it warns all data on disk will be overwritten)  Then after cancel I get:
   
So, I click okay to close out the window.
 
When I try CPAP importer in Oscar I get:
 
   
 
Which after 20 sec. or so changes to:
 
Find Directory
Look in:   C:\Program Files\OSCAR
C drive shows in window
Choose is grayed out
 
I'm not sure whether it's asking me where to find my SD card, or whether it's asking where I want the CPAP data to be put, or what?   If I try to navigate via the "My Computer" to SD card F drive via my computer, no F:\ drive is found.  I only see C and my external hard drive.

Find Directory
Look in:   (blank)
D drive and E drive   
   
If I type in F:\  in the line for directory and press enter  the window just closes, and nothing happens.
 
If instead I choose Owner  then "OSCAR_Data"  then press Choose

Find Directory
Look in:  C:\Users\Owner\Documents
Selection window, I select  "OSCAR_Data"

Then I press Choose, again, nothing happens.   Daily view and Overview etc continue to be grayed out.
I decided to revert to Sleepyhead (which worked well for years before my Win7 to Win10 update), and reloaded that.   However, with sleepyhead I get the exact same behavior.  So, I suspect the problem is tied to my new Win10 operating system, and its dislike of my cpap SD card.   Maybe it's just not willing to let Oscar download data from an SD which it thinks is not formatted?
 
I have another SD card from an older similar Respironics system One CPAP, but I also get the same results with that.   Putting my SD card back in the CPAP, respironics acts like it's fine with the card, so I think the card is okay.   
 
In all the switching and experimenting, I'm sure at least once I put the SD card in without locking it, but that made no difference.   I'm sure I'd failed to lock it once or twice when using Win7, and had no trouble either locked or unlocked SD with Sleepyhead.
 
I'm sorry if I'm repeating an old question.  I've searched in several places for a solution and came up empty.  Maybe I'm not a very effective searcher?
 
Thank you in advance if anyone is able to offer help.

It looks like your PC cannot find and does not recognise the SD card. Do you have another one you can try ?

[FortCollinsSleeper]

Yes. I have a second SD card from another similar CPAP. I tried that one, but got the same result. The 2nd one also has worked with sleepyhead as recently as 6 months ago.

Thank you for the suggestion.

Then maybe your card reader is bad or not using the correct drivers

Do you have another computer, or another SD Card reader?

[FortCollinsSleeper]

I just found 2 SD cards I use in a camera, which I normally can easily download pictures directly from the SD card. Both of these give me the same result with request to Format the disk. So, I think that narrows my problem to an issue with the reader, or some aspect of my new Win10 upgrade ability to interface with the reader. I'll talk to the guy who helped with the update, and I'll let you know what I learn.

Thank you!

I found a really old little Dynex brand USB remote SD card reader in an old drawer of device cables. I plugged it in, and it reads my camera SD cards fine. I put in the CPAP SD card, and fired up OSCAR and BOOM, everything is fine. Downloads fine from either of my CPAP SD cards, and seemlessly integrates the data. Nice! THANK YOU to those who responded, and especially to any and all who have worked on Sleepyhead or Oscar over the years. Your effort is very much appreciated by me.

Thanks,
Bruce

I didn't see if your reader is a USB plugin or a built-in device.  If it is a USB device, try another USB port.  Sometimes Windows will cease to recognize a device on a particular port.  If it is built-in, look at your system device listing to make sure it is showing up.
