WD Sentinel DX4000 - startup failed 0xD9

Hello

I have DX4000, and the following error shows in the led " startup failed 0xd9 ", any advise how to recover my data?

Thanks

do not attempt a WD recovery you will lose your data

you need to get raid recovery software. either google that or some have posted links in here.
you will need to connect your drives to a windows pc and do the recovery with the software

Thanks for your reply.
could you please recommend software?
