Anytime you poke your card into a Windows 8.1 computer it will write, or attempt to write, a file onto the card. Even if you do nothing else other than poke it in and take it right back out.
Then you will have to reformat the card on the Resmed machine.
1. You remember to "lock" the card before you put it in the windows machine and unlock it before you put it back into the Resmed machine.
2. You delete the dumb file that Windows 8.1 puts on your card before you remove it from the computer.
3. You tell the operating system you don't want it to do that anymore.
I use option 2. To accomplish that, I created a simple DOS script that deletes the stupid file and runs Sleepyhead, or Rescan whichever I am using at the time.
The DOS script looks like this:
cd "C:\Program Files (x86)\SleepyHead 0.9.8-1"
del "g:\System Volume Information\IndexerVolumeGuid"
rmdir "g:\System Volume Information"
You would copy this into a notepad document, change the file references from "g:" to "e:" or wherever your card is assigned, then save as name "sleepy.bat"
You would do a similar thing for Rescan, just substituting:
cd C:\Program Files (x86)\ResMed\ResScan3
for the first two lines.
You cannot really break anything so give it a try. But if you really aren't comfy doing this, then use option #1 which works swimingly.
For those occasions where you forget to lock you card, don't worry about it. The Resmed will reformat, copy all the important stuff back to the card, and begin recording the detailed stuff anew. You will only lose the 10 days or so of detailed stuff that was on the card before. After 10 days, you'll be back completely to normal.
Deep Breathing, thanks so much.
Retired Guy, thanks for the input. I don't know if I will use it since I am afraid of messing things up. However, I have someone who is really good with computers and I will have him review your suggestion.
I am a chemical engineer and also I read the scientific press. I am doing investigations into the entire biomedical engineering aspects of these systems.
Retired guy, I will lock the card. That part of your advice I will certainly follow.
