After some problems I decided to reset DX4000 to factory defaults including formatting all 4 drives (16 TB). Creating the stick lasted more than one hour. Now I see “RECOVERY STARTED” on the display and the PC-Program says that the harddisks are in formatting-process. But this lasts now fo 3 hour…

Seninel DX4000 Recovery Process is lasting much too long

It may take 24 hours or so. While it is thinking, did you check the hash of your download? If not do that while it is working.
