I've been trying to add an 8th drive to my RAID5 array connected to my HighPoint RocketRAID 2680sgl controller, however my array isn't being detected through the Web Management software. The array, and all drives are detected in the Bios utility on start-up, and I can see and access it in Windows, but this is what I see after logging into the Web Management software: This is what shows in Disk Management, with Media (D : ) being the RAID5 array, and New Volume (E: ) the new 1.5TB drive ready to be addad to the RAID5 array: I'm running Windows 8.1, and have installed the latest driver for the controller, and using the latest version of the Web Management software from the HighPoint website. I've also tried using the command prompt option, but querying the controller returns no info: I've been able to manage my array in the past using the Web Management software, but that was when I was running windows 7. Windows 8 is listed as being compatible on the HighPoint website, and I've tried running the software in compatibility mode. Anyone got any ideas as to why it's not working now, or anyone had any similar issues? Cheers.
