No. Nothing new. Too bad, we can't fix that volume then. It is weird that we find no volumes starting near the start of the disk. It appears the rebuild has done more than rebuilding or disk structures were even corrupted before the rebuild. This could also have consquences for iRecover.
I'd run iRecover one more time. After having selected the physical device (the array in single volume mode), select define volume manually. Pick the option "there was only one volume ....", then select the user input option and scan that.
If iRecover fails to come up with valid files, then it's one of two: either iRecover is making mistakes, or the volume is to inconsistent to rebuild. The latter can be verified by using another data recovery tool. My suggestion would be file scavenger from www.quetek.com
