ReadyNAS-Duo Upgrade fail

StephenB, thank you for that info. I'm curious, when you went NAS to PC, did you have a switch in the mix? What type? I have checked the network stats and there are no errors evident, but your experience gives me some useful ideas to attack the large file transfer issue. I know others have had the same problem, I'd be interested in hearing any of their troubleshooting experiences. BTW, I have checked cables and drivers.

I am presently using a Netgear GS724Tv3 (bought a few months ago). Before then I used a small unmanaged DLINK switch; I don't recall the model. Jumbo frames are off everywhere. 802.3x flow control is turned on (and I believe it was also on by default in the Dlink). That might be worth looking into, though it seems to me that if flow control is needed, it would be when the PC is writing to the NAS (unless the PC is running 100 mbit ethernet or wireless). My switch stats do show pause frames being sent and received on the Duo switchport.

BTW, I also have done large (terabytes) transfers between my Pro and the Duo (the Duo is presently a backup NAS) using NFS. And multiple gigabytes with rsync.
