I bought a used 3Ware 9500s-4LP raid controller from Ebay (the old 3ware 8506-4lp didn't support RAID arrays over 2TB, but it was working), installed it in my server and attached it to the SATA backplane with my 3 2TB WD Red drives.
I configured the RAID via the RAID bios (ALT+3 on boot) as RAID 0/1 and 5 – I tried them all.
Back in Windows, I installed the drivers and 3DM2 (latest from http://www.lsi.com/support/Pages/download-results.aspx?productcode=P00258&assettype=0&component=Storage%20Component&productfamily=Legacy%20RAID%20Controllers&productname=3ware%209500S%20series)
As i looked for the RAID drive in Disk Management, there was only the system HDD visible.
How can that be?
I tried everything on Windows Server 2008 R2 also, no change.
The server I am working with is a Maxdata Platinum Server 520 with an Intel SE7320EP2 Motherboard. Latest BIOS installed.

Problem solved, the lastest drivers (9.5.4) made problems - tried 9.5.3 which the support sent to me - they worked.
Still have to try 3DM2 if it's working now.
