[root@localhost guest]# dmraid -b
/dev/sda:    312579695 total, "PVF904Z21DEXXN"
/dev/sdb:    312581808 total, "PVF904Z21HYVDN"
/dev/sdc:    312581808 total, "3JS39NKF"


The third disk is not a raid member but I think is checked for the
raid1 rebuild. I don't understand why the sector numbers are different
in the first two disks...they are the same model.

If the problem is not only the metadata, do I have to install windows
to the third disk to rebuild or is there a boot cd/usb solution? It
should exist...

This is the first time I use raid and I didn't expect frequent
failures. Is there a way to prevent them?
