I am exporting some MXF Op1a files today and I am getting fairly repeatable crashes where it will cause the connection to my Terrablock to go away. All drives still show mounted in the connection tool but they no longer show in file explorer. I get the attached error which makes since because the drive is no longer connected. I have tried different projects, different partitions of storage, new user, uninstall/reinstall Avid with no change. I can export DNxHD quicktime files no problems. This only seems to be happening on 1 computer as well..

Avid 2018.12.3 on Win 10

Fiber or ethernet connection?

Try running an extended high bandwidth test.

Thanks to Dan at Facilis, my issue seems to be resolved! AVG antivirus was recently updated, after uninstalling and a couple of tweaks to the network card settings I am back to happy exports.

I was going to suggest you call them but was thinking you were out of support. Their support is phenomenal and they’ve been very good to me out of support. Can’t say enough good about Facilis.
