LS-WVL HDD Error - How Can I format new HDD?

[normality2000]

I was receiving an error on a second HDD disk in an Array that I use as RAID 0 (Disk 1 mirrors Disk 2).  I used the web interface to rebuild the Array but this did not fix the problem.  I then swapped out the disk that was being reported as an 'Error' for a disk that is 1TB larger than the other HDD.

Research and guidance suggests that I can format this disk in the web interface, but all the action buttons in the top menu are grayed out.

How do I format this drive so I can rebuild the array? 

Has anyone run into this problem before or is the LS-WVL destined for the trash can?

FYI: RAID0 means there is no redundency, post a screen shot of everything that is being displayed on the System/Storage section of the admin page.

I meant to say RAID1 ... however ...

I'm now getting a different problem.  The LS-WVL is now only booting in Emergency Mode. When I use the Updater ver 1.73, it seems to run and shows that it is transfering firmware but then I get an error message window that reads 'LS-WVL-EM529 returns an error. (ACP_STATE_FAILURE). Updating is aborted'.

Any ideas what this means and how I should go about resolving it?

Many thanks in advance.
