Help with set up of NAS drive on home network

First of all may I say hello!
I am in the process of setting up a gigabit network at home.
I have successfully installed a Edimax BR-6574n broadband router and a Buffalo HS-DH500GL conneted to the net via by a o2 wireless box.
Everything works fine until I try to copy files to the Nas drive after a few seconds it comes up with this message.
"Cannot copy filename: The request could not be performed because of an I/O device error."
I also get this message when I try to use my 16gb SD card in the onboard card reader.
I am assuming that it is a pc problem but all advice welcome!

many thanks,

Paul

long filename on a fat filesystem maybe?

I am ok plugging stuff in but start to get stuck past that!
I have just checked and all the file names are std dsc_00xx.jpg ones so I am not sure it is that, but thanks for the input, something to watch for.

The Buffalo NAS boxes use XFS not FAT, so you should have no worries about the lengths of filenames.

Hi,

Can I assume you are using Windows-type sharing so the Buffalo appears like another computer / server on the network (you haven't said if using a Mac?).

The usual stuff applies such as making sure that the computer name and that of the Buffalo are both 15 characters or less (otherwise you might find that the computer name - used in Windows sharing, and the hostname - used in DNS, are different).

Make sure both are in the same workgroup.

If the Buffalo provides access to the files via standard protocols such as
Windows file sharing (SMB/CIFS)
Apple file sharing (AFP)
FTP
HTTP

then you don't generally need to install any additional software to talk to it (though their may be some "discovery" CD for finding it and configuring it). Most NAS boxes have web configuration as long as you know what URL / IP they have.

Also, I notice that you have two routers, therefore:

If (a) the O2 wireless box is giving out IP addresses (via DHCP) and (b) you will only be using the LAN ports on the Edimax router, not the WAN port, then make sure the Edimax router has DHCP off

In this setup the Edimax does not need to act as a router, just a gigabit switch and wireless access point.

If however you have connected the WAN of the Edimax to a LAN port on the O2 box you will have to be more careful about how you configure the IP address ranges.
You would effectively have 2 distinct networks.

The devices on the "inner" network will be "double NATed" which some internet applications have trouble with.

Furthermore, file sharing protocols don't usually work in both directions across a router (which tends to block unsollicited incoming traffic while allowing outgoing.

You might need to describe what is connected to where if you are still having problems.

The SD card reader, is this one built into the PC, i.e. does not use network at all?

If so, then something more serious is going on, and a generic PC help forum to fix that is best bet first, as the solution for that may resolve the other one.

Some SD readers can only manage up to 4GB SD cards I believe
