I don't understand what that means - how can you have two failed drives, but hardware is ok? If you lost 2 drives out of a 3+1 RAID5, then you have essentially lost your filesystem, I'm sorry. > I check both driver on other PC with ufs explorer and drive is full of data, but xfs file system is not recognized. because the drives are part of a raid set, and they are not xfs filesystems on their own. https://en.wikipedia.org/wiki/Standard_RAID_levels#RAID_5 > How can I write manually on harddrive using raw data the beginning of xfs definition?? You can't. > I hope someone can help me because buffalo is very good in selling, but not so much in Support :(. If you lost 2 of your 4 drives, there's not much support to do, I'm afraid. -Eric _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
