 Is the capacity of the Hard Disk Drive to be rebuilt enough?
→ Use a Hard Disk Drive with the same capacity as that of the faulty Hard Disk Drive.

configuration information, initialize it, and recover the drive using backup data.

when the drive is installed.

the product.

→ Replace the failed Hard Disk Drive with new one, and then perform Rebuild.
 Is the Logical Drive RAID0?

configuration.
