When your co harts removed the drives, also the OS. If they kept any of the drives you could salvage the OS. 1 drive out of an RAID5 Array will do the be a data breach.

But there is hope. You can install FreeNAS on the box. You need to change/disable the watchdog in the bios. You must install the freenas on a PC then move the HD to the 4400. The easy way is to use a nic that is in the PC. That way it will have the proper drivers. Do the initial setup in the pc. Then move it to the 4400 and see if it will boot.

I have a Dell 715N (Hallis) which is a 4400 with out the special dip chip identifying the Snap. I have not had time to load the FreeNAS. My first attempt many months ago, made me hunt for the correct driver for the builtin nic. Then have not had time to try agian. You would need to add video card if you wanted to watch the boot. Normally you would use a null modem cable and a ternimal program to monitor boot process.

If you have access to another Guardian OS unit you can have it transfer the OS to new HD. It's a simple process, and would save you a lot of time.

Some one has allready done this on a 4500. Search the forum for it.
