I purchased this product as a heavy-tonnage fileserver to be accessed from Linux hosts exclusively via NFS v3. I was not interested in HTTP, FTP or CIFS(samba) file sharing. The NFS access was the high-order selling point (I would not have purchased it if CIFS was the only supported protocol).
The following details how to complete the configuration of NFS so that the uid/gid of NFS clients are respected on the server (not squashed). The default configuration is to squash all client uids/gids to 'nfsnobody' and export some parts of the server in readonly mode. There is no need to "break into" the box to remediate the deficiencies (ignore web sites that suggest such a procedure). This is your server, you own it, you are maintaining it to suit a standard use case that is normally accounted for. The Infrant (now NetGear) ReadyNAS NV-series units handle this use case out of the box. The Advanced Mode allows you to remediate the NFS configuration of the unit as an explicit product feature. Western Digital is to be congratulated for providing this forward-looking field-accessibility method.
Firmware revision 2.01.92 of 2009-07-31.
Assumptions:
1. The server is at a DHCP-configured IPv4 address. Another (Linux) client can mount /nfs/Public. You have created a new NFS "share" at /nfs/MyExample. Files & directories created from your NFS client are created with uid/gid "nfsnobody" instead of current system uid/gid.
2. NFS was not enabled by default when you boot the server for the first time [you enable it from the GUI as directed in the User Manual]
3. The default setup has NFS configured to export all partitions 'all_squash', 'root_squash' in /etc/exports. Certain partitions such as /nfs/Public are exported readonly; which is unhelpful. You will need to fix both of these problems manually by the method herein.
Remediation Method:
1. You need to get ssh root access to your box to modify the NFS configurations. You will need to be very careful doing this as is always the case with the unconstrained root privilege level. Use your power wisely (and keep records of what you do). Enable ssh root access from the GUI at System->Advanced->RootAccess[SSH Access] - enable. The factory ssh root password, is listed on fileserver's admin web page. Use it. Change it once you log in with /usr/bin/password (and keep records).
2. Using a (gnome-terminal) from elwewhere, login as root to your fileserver with 'ssh -l root' (and the password supplied by the filserver's initial configuration page).
3. See /etc/exports contains NFS configured inappropriately.
$ cat /etc/exports
/nfs/Public *(ro,all_squash,sync,insecure,anonuid=65534,anongid=65534)
/nfs/Download *(ro,all_squash,sync,insecure,anonuid=65534,anongid=65534)
/nfs/MyExample *(rw,all_squash,sync,insecure,anonuid=65534,anongid=65534)
4. Remediate the NFS access permissions as you desire.
mv /etc/exports /etc/exports.orig
cp /etc/exports.orig /etc/exports
vi /etc/exports
Change all export rules to be 'rw,no_root_squash'
5. Check your work
$ cat /etc/exports
/nfs/Public *(rw,no_root_squash,sync,insecure,anonuid=65534,anongid=65534)
/nfs/Download *(rw,no_root_squash,sync,insecure,anonuid=65534,anongid=65534)
/nfs/MyExample *(rw,no_root_squash,sync,insecure,anonuid=65534,anongid=65534)
6. /usr/sbin/exportfs -a
Done.
NFS now creates files with the client's NFS uid/gid and you may be root on the client and act with rights on the server.
Others have reported issues with the media-serving against the 4T unit (see that page). Perhaps those issues can be remediated, applying suitable care and knowledge, with the root shell access feature.

As the title indicates the setup for this network drive was very simple and did not have any issues accessing it from XP, Vista, and Windows 7 laptops. The next hurdle will be trying to access it from my Linux laptop.
The only issues was trying to access the data from a remote location. The software provided links you to a file sharing company which charges a monthly fee. However, they do not support 64-bit operating systems.
That being said this file server is one of the slowest drives I have ever worked with. I have it setup as the default RAID 5 (striping with data reducndancy). It is suppose to get the speed benefits of RAID 0 but with the data reducndancy of RAID 4. The best I have gotten is a transfer rate of 1.1 MB/s (USB has been around 16 MB/s) so transferring 250 GB can take up to a week.
This product is nice and compact as well as quiet and produces low heat. The USB connects are only for backup (you can plug in a USB device and the WD fileserver will copy it probably faster than it transfers over the network - I have not tried it yet). You cannot share the devices that are plugged into it.
This product is perfect for storing large amounts of data but do not expect speed adequate to run appliations from it or transferring very large files quickly.
