Hi! Welcome to the forum.
Sadly, Phatnoise no longer maintain their servers, which is why you are seeing these errors.
However, there is an alternative that does the same job, only better! See this thread....
http://forum.phathack.com/index.php/topic,1641.0.htmlThe tools will allow you to rebuild your DMS and set up any new firmware options as needed.
But there is one very important question that must be asked... I assume that your Phatbox has not been hacked to take a non-Phatnoise sourced hard disk. So when you "wiped" the drive, what did you do? If you used the Phatnoise tools then it should be OK. If you used Windows or similar to completely re-partition the drive then you will quite likely have a problem. The non-hacked Phatbox will check for some signature bytes at the start of the drive, before the first partition. If you re-partitioned then they will have been lost - they are specific to each drive - and that will prevent the drive from working. If they are still there you should be OK.
Once you have things working again, I strongly recommend that you take the next step and apply the hack to your box (again using the tools). But please, get it all working first. Folks here can help you, but it makes life easier if things are taken just one step at a time.
Please come back to this thread if you get stuck or need more information.
Good luck!
