                        <content:encoded><![CDATA[I had RAID setup with 2 OWC Accelsior drives in my 2010 Mac Pro.  Crazy Fast.  But after power loss and a failing UPS, everything crashed and the RAID volume would not boot the computer.  I restored from a backup and was unable to make the RAID work, so I just used one Accelsior drive.  (so now non-raid)

Problem:  The other Accelsior does not appear in SoftRaid Lite at all.  It does appear in Disk Utility, but Disk Utility will not let me erase or partition the disk-- it has 3 unmounted volumes.  First Aid completes successfully.

I'd just like to use the Accelsior as a regular drive.  I'll try the RAID setup again at a later date.  How can I regain use of the Accelsior?  

Here is some info from Disk Utility:
