Default Windows 10 reported to damage WAV files on CF & SD cards

There appears to be an issue with Windows 10 setting encryption bits on WAV files on SD or CF media.

Sound Devices was the first to report the issue, I think: http://www.sounddevices.com/news/sou...echnical-alert

It's a thread on answers.microsoft.com http://answers.microsoft.com/en-us/w...2-661e47419b80

apparently it isn't happening with clean installs? It appears to be a service-related thing...

Connecting the zoom and transferring may be different than removing the card and inserting into the computer FYI assuming you have a similar zoom as I which works that way.

On a side note, what is a bit funny about that issue is (IIRC) you can't actually copy EFS encrypted files to a FAT32 drive without the OS decrypts them first (because EFS only works on NTFS). So that makes me think the data may not actually be corrupted but rather some flag improperly set making the OS think they are encrypted. Especially since EFS is a fairly explicit action/setup that has to be taken at some point earlier which these users apparently had not done.

This is HUGE.

I use SD cards (and FAT32 formatted USB drives) to move audio and video data around all the time. (Terabytes each week) Many others must do the same.

I am glad that I found out in time. Of course, these days I am very slow to adopt new tech for this very kind of reason. Seems to me that this is grounds for a lawsuit to recover damages for users time and cost to recover data.

This is clearly negligence by Microsoft, and negligence CANNOT BE WAIVED by any "user agreement" (even if there is a negligence waiver clause in the agreement).

Reminds me of the Sony "Rootkit" problem a few years back.
I think that problem cost Sony upward of $500 million to fix.

So, thanks for the warning Fran!
