How to reformat the RAID volume
1. Within Windows, click Start > Windows System > This PC.
2. Right-click the D: drive and select Format.
3. Choose either a quick format or full format. Do one of the following only:
For a quicker disk operation and less data security, ensure the Quick Format option is selected and click Start.
For a slower disk operation and more data security, clear (disable) the Quick Format option and click Start.
The D: disk drive volume is now being reformatted. This either deletes and recreates the file system structure only (quick format), or it overwrites all data on the volume with empty bits (non-quick format).
