DX4000 - Compatible replacement drive

I have a DX4000 w/ 4 - 3TB drives (12TB tl) - OS: 1.7.3.13, Windows Storage Server 2008 R2 that had a drive failure. The original drives were WD3009FYPX-09AAMB0 (3TB).

The WD30EFRX (3TB) red drive did not work - the drive that did work was WD4000F9MZ-76NVPL0 (a 4TB gold drive) that was recognized with no problem. Didn’t require “drive enabler” or anything else.

The volume is still updating / rebuilding after the swap - will update when done…

How did it go ?
I would recommend to use the ‘drive enabler’
My DX4000 presently has one original Re4, an Se1, a refurbished Re and a RedPro - all were accepted and installed no problem as the original Re4 disks failed.
