I tried to run optimization and garbage collection with no luck. The main folder is DFS replicated and still doing initial sync - this may change files, but dedup is configured to dedup files after 0 days.

I managed to get around the problem a bit. Yesterday I started a garbage collection job with the -full parameter. This didn't do anything, but I found some sources on the internet that stated, the -full switch was not supported.

Therefor I started another garbage collection without the -full switch and it cleaned my drive to the original values - even the dedup statistics went back to normal thereafter. Or are chunks immediately deleted after they are un-deduped? However as the initial replication is still running and dedup schedule is set as 0 days, I think we can first eliminate one of them to see if issue could be fixed. So please test to disable Deduplication until initial replication is done - disable Deduplication could help you get rid of the current situation and if the issue is DFSR related, after initial replication is finished, files will not be edited so frequently which should help on this issue.

Note: In order to speed up the initial replication, you can copy files to target server as a pre-staging so that data will not need to be replicated through DFSR. And if files will not be change during replication, you can use the new function of Windows R2 that to copy metadata to target server.

You can also set Deduplication schedule back to 5 Days the default setting - You may need to redo an optimization to un-dedup all files similar to disable dedup first to get rid of current situation. As the schedule is set to 5 days, files will not be dedup immediately which should also help on this issue.

I hope this helps but it might not since you are using streaming data as a input, where as I was using data I created and wrote into the file to be read back.

The mmioDescend method in Windows 7 returns a different chunk size than in previous versions of Windows.

This call is being made on a WAV file that is being streamed down, so the user may begin playing the audio before the entire file is streamed.

Previous versions of Windows would return the chunk size as stated in the file. Windows 7 seems to be truncating this size based on the current file size. Is there a way to get Windows 7 to return the chunk size as stated in the file so that it is compatible with previous versions of Windows?
