Does reading the data card erase the data?

RE: Does reading the data card erase the data?
I responded in another thread, but this is probably going to be popping up more, so I'm reposting here...

Windows 8.1 creates a directory and file "\System Volume Information\IndexerVolumeGuid". (The folder is hidden, but you can see the file by opening your card in Windows Explorer and manually entering the directory in the location bar.)

Their presence seems to confuse the ResMed and some other equipment. If you forget to lock the card before using it with Windows 8.1 and your ResMed wants to reformat the card, choose "No" and put the card back in your computer (still unlocked).

You can remove the directory and file from the command prompt (or a batch file) with the following commands (for an SD card in drive F: in this example):

del "F:\System Volume Information\IndexerVolumeGuid"
rmdir "F:\System Volume Information"

It should then be accepted by the ResMed without reformatting.

You can add "/s" to the second command and then skip the first (file delete) altogether.

rmdir "F:\System Volume Information" /s

You can also add /q to avoid the prompt "Are you sure (Y/N)?"

Also, "rd" is sufficient for rmdir.

Or, optionally, let the Resmed reformat the card. It will automatically rewrite all of the summary information, and in a few days it will have re-populated all of the "detail" data it can keep on the card, and no one, other than you, will ever know!
