Reconstructing a RAID 0 or 5
Use this dialog to reconstruct a broken RAID. Do not use it if the RAID is not broken even if it has been reformatted or corrupted. For more information please read

RAID Analysis Service.
You can select the disks in the correct order in the RAID. In hardware-based
RAID, the order is usually the hardware order, such as the SCSI ID from the smallest to the largest. In software-based RAID (including NAS), the operating system may choose a random order.
For hardware-based RAID, choose Entire disk. For software-based RAID (including NAS), choose the correct RAID partition.
Specifies the starting sector number of the RAID area on this disk.
In software-based RAID (including NAS), this value is automatically filled in when you choose the RAID Partition.
In hardware-based RAID, this value is controller-dependent and is the number of sectors at the beginning of the disk used by the controller to store RAID configuration information. For a RAID controller that uses its own onboard non-volatile memory (about 90% do), this value is zero. When the value is not zero, it is very difficult to determine and you may need our fee-based RAID analysis service.
Adds this disk to the set.
Removes the highlighted disk from the set.
Disk extents or component disks
This table displays an ordered list of the disks.
Move up, Move down
Rearranges the order of the disks by moving them up or down the list.
For each disk
With few exceptions, you should use the default value which is the size of the
smallest disk less its First Sector value. You may need to use a different value if the RAID is software-based and there are other partitions sharing the disks. Type in the size (in megabytes) of the RAID extent per
Total volume size
This value is computed from For Each Disk. For a RAID 0, the total size
is this value multiplied by the number of disks. For a RAID 5, it is this value
multiplied by the number of disks less one.
The maximum value you can specify in For Each Disk.
