Try mdadm --examine on the raw devices and any partitions you can see. If mdadm recognizes the meta-data format there is a very good chance the array can be brought online, try to do that in read-only mode (read the mdadm manual). Examine the result, it may contain partitions or a filesystem that can be mounted via something like ntfs-3g. If you get that far I recommend running a CHECK on the array (Before making it read/write) and validating that there are no errors. If you get errors you /may/ want to make a backup of the entire device. I know that old drives from a 4-port hardware raid card I used one time kept showing meta-data (in the syslog) unknown/not recognized, but I don't believe it was a highpoint 1640. There have also been improvements since then. -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
