I'm trying to copy about 120GB of data from a Buffalo Linkstation NAS to a newly purchased DNS-323 using the Ubuntu Linux KDE file browser and the copy never completes. Both NAS file systems are mounted on the Ubuntu system. I'm trying to replace the Buffalo box with the DNS-323.

Usually 10-30GB of files copy and then Ubuntu reports a file error on the DLink. Unfortunately it's nothing more specific than a file error. The failed file and the time to failure varies on each attempt I've done. After the failed copy, I just removed the partially copied directories/files on the DNS-323 and start over only to have the failure repeat at another point.

I have several options here (which I have yet to try):

1) From a Linux terminal, mount shares from each NAS and do a tar.
2) Use a Windows-based client to copy files.

I have successfully used the Ubuntu browser to copy the 120GB from the Buffalo to:

1) The local drive on the Linux box
2) A Debian-based NAS also on my network. (i.e. each NAS was a mounted file system and the Ubuntu client moved the files).

The problem only occurs when the DNS-323 is involved.

I'm more of a command-line Linux person anyway so I'll likely just go with the tar but does anyone have any thoughts on reasons for the failures?

Setup:
The DNS-323 has 2 newly purchased Western Digital 1TB WD10EADS drives
Raid-1
No flashing sync light or amber failed light
All wired Cat-5 in the house w/100Base-T
Throughput to/from the DNS and the Linkstation is between 35Mbps and 75Mbps for all clients (speed is decent)
Static IP on the DNS-323, Buffalo NAS, and the Ubuntu client
No FTP, media, BT, etc features enabled. Just a plain vanilla NAS setup.
Firmware = 1.07 as shipped from DLink.

Thanks.

Something is certainly amiss!  I have 800gigs on my DNS-323, and I copied it all to the DNS-321 that I have.  I then replaced the two 500gig drives in RAID-0 with two 1.5TB drives in RAID-1 and copied all the data back.

There were no errors in either transfer, and all the files arrived intact.  This was done using Windows 7 64 bit final-release version.

That's an understatement!

Well I found the problem and it's a big D'oh on my part. Prior to trying the copy with the KDE browser, I created a csh script to recursively copy from the Buffalo to the DLink. This script was fired off in the background. I killed the main process and decided to use the browser copy but forgot about the child processes it spawned.

In short, the failed copies were due to the browser copy colliding with the background copy processes. The same destination files were being written at the same time (very bad).

Must have been bit soup!

Good that you figured it out.
