Using a Disk from Another Decommissioned RAID Array

Before you can reuse a disk from another RAID array, the disk’s superblock must be zeroed per the following command:
# mdadm –zero-superblock /dev/hdc1 –force
Note: The equivalent to the superblock on Microsoft Windows filesystem is the file allocation
 table (FAT), which records which disk blocks hold the topmost directory.
