Drive Error on LinkStation LS-WV4.0TL/R1

[Lamda]

Hello everyone,,
Linkstation LS-WV4 which is out of warranty. Flashing read light on front of unit. Navigator said drive 2 error. I purchased an exact duplicate of the drive and replaced it. Still have drive 2 error and now Error 22.

I can't format drive 2. When I select drive 2 the format button is grayed out. Works fine for Drive 1. Array 1 is listed below, is this the cause of not being able to format drive 2? How can you delete an array?
