File corruption with CIFS?

[Narann]

Hi FreeNAS community.

I always have file corruption with CIFS. :(

Almost 1/10 of copied files became corrupt... (I've moved all my personal photos. You can't imagine how I'm sad... Seriously).

There is an example of corrupted jpg:



I have problems with every kind of files but it's very visible on jpeg.

The fact is there is no problem at all with NFS Share. So I need to store files I want to move in local, boot on Linux and do the copy...

That's why I think it's CIFS related. No problem with NFS. Has if CIFS lost some data packs...

There is no way to check data pack integrity? To avoid this kind of problem?

Could it be related to this bug?: https://bugzilla.samba.org/show_bug.cgi?id=8559

Please, help, I'm very sad from this situation... :(


My Freenas informations:

Don't hesitate to tell me if I've forget some informations. I really would like to solve this problem.

Have a good day and I hope you will be luckiest than me with FreeNAS...

PS: If any of you have any software that could help me to repair my poor jpeg files, don't hesitate too! :(

After some investigations, I've first think it was my network card or my switch but I have more and more the impression this is related to my Avast antivirus. I've desactivated it and it doesn't seems to create corrupt file anymore (I use a python script to test data integrity between two files).
