How do I create shares on the second drive?
When the hard drives are used as two independent drives (non-RAID), it is only possible to create shares on the main drive. The path to the drive is fixed, so it is not possible to create shares on the second hard drive.
It is however possible to access the second drive via network (SMB or FTP) but all files stored on that HDD will be similar to the public folder. All users have access to it and can modify the files.
