Tom,

If the camera _is_rebooting that may mean that the power supply is insufficient. Internally in the 12V version we use 9-36V DC-DC converter, but as the camera has input diode bridge, the DC-DC converter gets less, than the full input voltage. So the margin is not that large, and when the hard drive starts spinning, it can cause the short voltage drop and the DC-DC fails to provide internal 3.3V. Your camera has additional boards (10359, 10338) that causes more power consumption than a regular 12V camera with HDD, and while we tested it working we did not verify the margin.
that is starting to make sense as it reboots when I am trying access the hard drive
What power source are you using?
the one yous supplied
Can you try it with higher voltage (it can go up to 36V) to verify the problem? 

I'll have to do some hunting round the house to see what I have got (crossing fingers)
Andrey

Tom, 

The only case when your laptop ( ubuntu 10.04?) can lose wired connection is when there's no link - the amber led should go off/on and that should cause the camera to reboot. And the camera won't reboot, right?

the camera is rebooting... it just happens when you least excepted to...

Please, try the following:

1) Check how the amber led behaves when the pc loses its ip address.
the computer dose not have the amber or green ethernet lights
on the camera the light amber led dose go off then on again

2a) Disable wi-fi - in case your OS can't handle 2 networks at the same time.

i'll have to looking into that
or
2b) Make it so the pc won't lose its ip address when
 something is plugged/unplugged - it's not trivial (if not impossible) in (k)ubuntu's network manager =)

or
2c) Change the camera's IP to 10.0.0.xxx (192.168.0.9 -> System Preferences) and plug it to your wi-fi router - that would be the most effective solution of the problem.
my router has an option to have 
group of DHCP Pools, I tried to enable a 192.168.0.X network for the camera, but gave up
I do have another router siting around...... (thinking)....

Best regards,
Oleg Dzhimiev

I am have hard drive/disk Recorder issues

the Disk recorder gui sometimes mounts the hard drive

but by the time I can do something (record/view/download videos) the network disconnects

Tom, can you please be more specific - what does that mean "network disconnects" ? Is it something related to the camera, computer or some router/switch?

the computer is connected directly to the camera 
the computer report the network has been disconnected and then reconnected

I try refreshing the page, and I get can not connect to 192.168.0.9

Refreshing the control page while it is running might have some side effects.

I forced to disable my ethernet connection and re-enabling it

I then refresh the page and the issue starts again :(

What do you mean by "disable my ethernet connection and re-enabling it" -is it in the camera or on your computer? 

on the computer

What actions/command do you run? Can you provide additional information about your network configuration? 

the computer has two networks
camera to computer (computer: 192.168.015 camera 192.168.0.9)
WIFI network (10.0.0.X)

Andrey

if a screencast can explain it better I can do one?
