Hi! I suggest you to try a different network card. Your described different transfer combinations let me suspect a kinda buffer overflow in either the network card or the connected gigabit switch. The data corruptions only seem to arise when the data stream is coming too fast through the network devices, from the internal hard disk of the WinXP-SP2 Desktop system. In these cases the transaction works: 1. when the source is "slow" enough (connected USB disk, Laptop disk)) 2. when the transfer passes the slower 100MBit switches 3. when the target in the gigabit network is slow enough, it should work as well These circumstances let me conclude to give the network card exchange a try. You also could try to connect another PC via gigabit connection instead of the Thecus to make a copy to. If this combination would work, it would be a sign for the Thecus to be the reason for the corruption. I hardly can wait to read about your results...

MasterBlaster -- Thanks for your response.
I've tried 5 network cards with basically the same results. The two built-in 10/100 cards on my ASUS A7N8X Deluxe board, and also 3 separate PCI Gigabit ethernet cards: DLink DGE-530T (current card), a Linksys Card I tried, and a TrendNet card I tried.
Thecus Support has entirely stopped responding to any of my pleas for help, nor have they ever actually suggested ANY troubleshooting steps other than "run an MD5 hash before and after to verify the files are corrupt". They haven't asked me for any system logs, network trace files, etc. I still do not feel comfortable shipping my unit with my hard drives in it to them as they have requested as I doubt I'll ever see the drives again. As far as I can tell Thecus' support department is rather incompetent. I have also asked them many questions about other features and what they will support in the future and they have entirely ignored my questions every time. RATHER unprofessional behavior.
I have been busy the past couple of weeks and have not yet had time to continue testing. However what I have noticed now is that I can successfully copy data to the N5200BR from any computer EXCEPT my Windows XP-SP2 destkop system which results in corrupted data. From the WinXP-SP2 system I also get corrupted files when copying to anywhere else on the network. Copies work ok when copying disk-to-disk in the system. I will be attempting to do a virgin install of XP and testing data transfer again, perhaps it is something installed on my system.
As ironic as it is, in the midst of all of this one of the hard drives in my system crashed just after I backed up all of my important files to DVD's, but I still had to spend an entire weekend doing data recovery. Thankfully I did not lose anything critical, however, the reason I bought the Thecus system was to add yet another safety-net to my precious data...
Thanks to everyone who has helped thus far; I am still looking forward to solving this and welcome any additional suggestions anyone might have.
