Unfortunately had a failure at work and the machine blue screened when attempting a rebuild (for whatever reason), but that is a moot point, what's done is done.

In an attempt to get it to pick up the array again the configuration data was removed and then re-added, the array is back online but the data isn't readable in windows but chkdsk has detected the NTFS filesystem present on the volume, could it be possible that the RAID headers are now incorrect due tot the configuration change?

What can I try to attempt data recovery at this stage?
 
I'm guessing you can't just restore from your backup? Oh well, something to learn for the future. :)

Is it a proper hardware raid solution ?

If so try booting off a Ubuntu USB and having a look there. I often find that linux does a better job of looking at imperfect NTFS partitions than windows does.

I assume that the backups aren't a viable solution for whatever reason ?
 
Is a particular disk marked unusable in the RAID controller? Guessing it's not giving you the option to repair the array?
 
Used mdadm under Ubuntu, I was able to mount the volume and pull most of the data off.
