TrueCrypt container
Hi I currently store a few TrueCrypt containers on my ReadyNAS 316. I use TryCrypt to mount these containers when i wish to copy/paste additional files into the container. This has always worked f...

I have a new local build of the SMB Plus app that adds an option for this setting. Get it from here, and install from the Apps tab, using the Upload button. Then launch the SMB Plus app, go to the Write Options tab, and disable Strict Sync.
We plan to make this a per-share option in a future firmware release.

The GUI definately says CoW is off. Is there another way to confirm that? Maybe that's the issue, but I would expect that to have similar effects on both container types. No encryption enabled except that Veracrypt is encrypting on the PC before storing.
As for fragmentation, filefrag says the Veracrypt container has 1277 extents and the .VHD has 14212 on the 6.9.1 system.. The Veracrypt one has 796 on the 6.8.1 system and I dind't do a .vhd on it. I find that number of extents on the .vhd very odd, as it was created after the Veracrypt one and there should have been plenty of space to be mostly contiguous.
For my use, I can probably move to .vhdx files (though I didn't check that yet -- only checked .vhd). I have always used TrueCrypt/VeraCrypt ones because they are more robust than .vhd. But .vhdx is supposed to fix that and I no longer have a need to access them from Win7. But for anyone that actually needs encryption or access by something other than Windows 8+, that's not an alternative.

lsattr will tell if it is off for a specific file (the "C" attribute is set if CoW is off - backwards from what you might think).
If it isn't set, try creating a subfolder from ssh, and then set +C on the subfolder with chattr. Then copy the container into the subfolder. C should be set on the copy.

Just checked, and the "C" attribute is there.
