Reinstall Whs 2011 Without Data Loss.

Hello WGS community,

I've been fruitlessly in search of a guide to reinstall WHS 2011 without losing my data.

Here's the setup:

WHS 2011 installed to a 120gb ssd without any other partitions utilizing full ssd space.

Data is on d: drive consisting of 6 x 3tb red drives  to an Adaptec 6805 controller configured as Raid 6 array.

Messed up my WHS install and need to reinstall without losing any af the 8TB data on the array.

No backups were used in any way of course (yeah I know...)

Is it just start new install, then install raid drivers and point to the array for the serverfolders and recover existing data or is there an obscure caveat I need to watch for.

Thanks for any response.
