DEV/SDA is automatically partitioned when the system is installed;

Dev/sdb for manual formatting

DEV/SDC and DEV/SDD are temporarily not partitioned.

Mount Disk

Temporarily create a directory on your local hard drive /wwwroot

and mount a partition from the second hard drive/dev/sdb1 to /wwwroot

See if the mount was successful.
