"Solved" Raid5 recovery chalange

Guys hopefully you will be able to save me some time...

Scenario: 4x1tb black's on ich10r, default settings raid5 with one partition.
Two drives failed simultaneously, i manege to get one back online, and i have a new 1tb black.

I had similar problem at work, but both drives was ok, in that case (PSU problem) so i deleted the raid, created a new one with same settings and i was able 2 fully restore the partition with "testdisk". lucky
Now in my current case i tried to do the same, but i have one drive blank. So far it didn't find what i need. i wonder, if i disconnect the blank drive and make the array degraded again, will it help? Or you guys have a better idea. I hope that i will not have to recover the data to a different drive...i have a lot of crap on that drive and data can get corrupted...
I will be able to get all or almost all the data back, but you know how long it can take with array this size
All the drives with tler fix btw....
OS w7x64, not that is mater...
Any advice will be appreciated...

Dude i don't think you have read the question...if 2 drives failing on ich10 you cant rebuild no meter what you do....the only think 2 do is delete the array, and than create a new one. And with some luck recover the lost partitions or data....
