Hard Drive Won't Mount (Doesn't show up in diskwarrior.)

Hey guys,

I'm having some major problems with my RAID 5 set up, and I thought one of you might have a solution. I have a 3-month old OWC Mercury Elite-AL Pro Qx2, with four 2TB HDDs.

Last night, the drive disconnected randomly and is now not reading properly on my computer. When I plug it in I get this error:

'The disk you inserted was not readable by this computer.' 'Initialize, Ignore, Eject'

There is crucial information on this drive, since it's in a RAID 5 configuration, I'm assuming that the hardware is OK, and this is a directory problem. However, the drive is not showing up in Diskwarrior, and First Aid is grayed out in Disk Utility (It appears as a 6TB External RAID).

Can anyone suggest anything I can do to fix this device?

Thanks,
Adam
