raid5 system degraded and on boot can no longer log on

Hi everybody,

to begin with: I can create raids in linux but that is about it. I am quite inexperienced.

I had created a raid5 setup of which one drive failed. This resulted in a degraded setup. After this happend it continued to work for a while afterwards (not recommended but no possiblity to replace the drive)

After a while the whole md0 stopped working and upon rebooting I get an error that I cannot mount md0 because there is something wrong with the superblock.

I tried to reconstruct the raid by building a new raid5, this didn't help very much. I did not recreate the filesystem as I thought this would destroy the information on that disk. Using some software I did see that most data was still available on the disk, but not in the right way (windows system with a raid recovery tool on another disk)

How can I reconstruct the raid5 in such a way that I can copy all information off the disk? Can anyone please tell me how? or point me to a beginners tutorial / wiki? 

thanks!
